Titolo: La telefonata impossibile. Perchè non funziona?

Non ho ancora conosciuto qualcuno (neanche per sentito dire) che sia
riuscito a telefonare tramite modem con cuffie e microfono collegate alla
presa mic e spk.
Io stesso non ci riesco e da secoli ci provo, ma il problema è sempre lo
stesso. Io sento quello che l'altro dice, ma lui no?
Come è possibile? se un modem è Voice, non dovrebbe farlo automaticamente?
Ci vuole una stringa apposta? le ho provate di tutti i colori!
Il NG è l'ultima speranza, dopodichè metterò a monte.
Ho provato anche a installare i driver "Wave device for Voice Modem", e li
ho impostati come periferica prferenziale di registrazione e riproduzione
dal Pannello di controllo, ma non è contato nulla..
Se qualcuno potrà essermi d'aiuto lo ringrazio un casino......

Ho provato, ma non funziona nemmeno a me :-((((
Saluti,

 presa mic e spk.
Io ci sono riuscito :)
Ho dovuto litigare con Supervoice e poi i risultati erano comunque 
scadenti (non c'e` stato nessun bisogno di settare la velocita` della 
seriale a meno di 115200).
Sono anche riuscito ad usare la modalita` SVD con la quale ho potuto 
comunicare con il mio interlocutore scrivendo tramite un emulatore di 
terminale e parlando contemporaneamente.

Se ti riferisci al telefonare: se me lo ricordassi te lo direi.
So solo che non ci sono riuscito subito, ho dovuto provare un po'
tutti i tasti del "telefono virtuale" di Supervoice.
Per la "Simultaneous Voice over Data" ho dei documenti a 
riguardo: non appena posso mettere le mani sul mio Pc di casa li
cerco e vedro` di postare qualcosa.

Per la connessione ho utilizzato Hyper Terminal e la modalità definita
headset (#VLS=6), la quale prevede l'uso di cuffie e microfono collegati al
modem (se avete collegato l'uscita audio del modem all'ingresso LINE-IN
della scheda audio potete usare le relative casse), per entrambi i modem.
L'inizializzazione dei modem è stata fatta digitando le stringhe prima della
chiamata.
Entrambe le controparti devono impartire
AT&FX3 (è la configurazione più comune ma penso che si possa personalizzare)
AT-SMS=2-SQS=2#VLS=6 (corrisponde a selezionare la migliore tra le possibili
modulazioni dell'audio e al modo headset)
A questo punto uno dei due effettua la chiamata
ATDTxxxxxxxxx
e l'altro risponde con
ATA
Alla fine dell'handshake, se tutto è andato bene, si può scrivere e parlare
contemporaneamente :D
Se avete voglia di sprecare qualche scatto telefonico può essere divertente
provare.

Quello che segue è un documento della Rockwell che illustra come si può
utilizzare la modalità AudioSpan (il nome che la Rockwell preferisce usare
per la modalità Simultaneous Voice and Data o SVD).
Vorrei far notare che nel suddetto documento le opzioni del comando #VLS 5 e
6 non sono coerenti con quelle da me utilizzate.
Io ho potuto verificare personalmente che per utilizzare la funzione
AudioSpan-Headset tra due modem dotati del chip Rockwell RCV336DPFSP Rev
44BC il valore del comando #VLS va posto a 6 e non a 5.
Altre informazioni sulla modalità audiospan possono essere reperite nel
documento 1048R4.PDF (pag. 67) della Rockwell
(
http://www.nb.rockwell.com/techinfo/pc/resource_files/at_commands.html
).
Anche in tale documento i valori di #VLS non sono coerenti con quelli che
funzionano con il mio modem.
Enabling the AudioSpan feature of your modem will allow you to
simultaneously speak
with your remote opponent while playing your favorite interactive games.
Please read the General Technical Notes section first. It describes basic
terminology
for AudioSpan and details the initialization strings you must enter to
enable AudioSpan
to operate with your headset, speakerphone or handset.
If you're not sure that your modem has AudioSpan capability, please see
"Making sure
you have an AudioSpan modem" below.
Also listed are specific configuration notes for your operating system.
These include
general information to help you maximize your AudioSpan modem experience
under Windows
95, Windows 3.1x or MS-DOS; and suggestions on how to set your software to
work with
AudioSpan.

 -----------------------------------------------------------------------
General Technical Notes
AudioSpan-enabled modems will work on just about any game or application
software that
allows users to connect via modem. AudioSpan allows you to connect with
other AudioSpan
users to play games or send files while speaking to them directly in real
time over the
same phone line!
AudioSpan modems operate in three distinct modes: Handset Mode, Headset
Mode, and
Speakerphone Mode. The "14.4" and "28.8" numbers in following sections refer
to maximum
data rate (in kilobytes per second) when voice is not present during a
simultaneous
audio/voice and data communication (SAVD) connection. The data rate in SAVD
mode is
lower when audio/voice is present.
Handset Mode:
  Rockwell AudioSpan 14.4, Handset  AT-SMS=2-SQS=1#VLS=0
  Rockwell AudioSpan 28.8, Handset  AT-SMS=2-SQS=1#VLS=0
Handset mode refers to the telephone speaker and receiver that you hold to
your head whenever you make a regular phone call (i.e. your normal
telephone).
In handset mode, you have two choices for operation:
   1. You may call the person you want to connect with by dialing with a
standard phone
      and talking to them through the handset. With the proper handset
initialization
   string, you may then start your multi-user application (game, whiteboard,
etc.)
   without having to redial or interrupt your current connection.
   2. You may also set your application to Handset Mode and use the program
to dial the
      other party. After the connection is made, you may at any time pick up
the
   handset and begin talking.
Headset Mode:
  Rockwell AudioSpan 14.4, Headset  AT-SMS=2-SQS=1#VLS=5
  Rockwell AudioSpan 28.8, Headset  AT-SMS=2-SQS=2#VLS=5
Headset mode refers to any setup that includes headphones with a microphone
attached.
This setup is connected to the ports labeled microphone and headphone
located on the
back of the modem. This hands-free configuration gives you the freedom to
play games or
give presentations without the need to hold a receiving or transmitting
device.
For this mode, you'll need to set your application by supplying one of the
above
initialization strings. Once connected, you and your party can begin
speaking through
the microphone of your respective headsets.
Speakerphone Mode:
  Rockwell AudioSpan 14.4, Speakerphone  AT-SMS=2-SQS=1#VLS=6
  Rockwell AudioSpan 28.8, Speakerphone  AT-SMS=2-SQS=2#VLS=6
Speakerphone mode refers to any external receiving and transmitting device
usually not
attached to the user. A typical example of this is a phone that allows you
to speak and
hear your party without lifting up the handset. Another configuration is
having a table
top microphone to transmit your voice, and speakers to receive the other
party's voice.
In Speakerphone mode, you'll initiate the call directly from the application
before
beginning your multi-user session.
Plug and Play Issues
The AudioSpan modem you own comes in one of two flavors: Plug and Play or
Non-Plug and
Play. The initial modem setup differs according to the type of modem.
You can determine which type of modem you have by referring to the
documentation that
came with your modem. Generally, Non-Plug and Play internal modems have
jumpers on
board to configure the COM port and IRQ. The Non-Plug and Play external
variety assumes
the COM port and IRQ values of the COM port it is physically attached to.
These jumpers
are replaced by a PNP chip located in the modem.
Non-Plug and Play Modems
To install your modem, follow the instructions included with your modem. An
external
Non-PNP modem will require you to determine which COM port is available and
its
corresponding IRQ. Once this is known, you must change the jumper settings
on your
modem card. With your computer turned off, insert the modem board into an
empty slot on
your computer's motherboard. When you turn your computer on, you will need
to complete
the installation according to your modem's documentation.
For an external modem, connect the appropriate cables from the back of the
modem to a
COM port on your computer.
If you are running Windows 95 on your machine, Windows will detect the
presence of your
new modem and prompt you to complete the installation. If you are running
MS-DOS or
Windows 3.1x, you will have to run the installation software provided by the
modem
manufacturer. Again, follow the directions that came with your modem.
Plug and Play Modems
For a Plug and Play modem, setup will be much simpler. Again, follow the
manufacturer's
instructions. For internal modems, this will involve inserting the modem
board into an
empty slot on your computer's motherboard and turning on your computer.
External modems
simply need to be connected to a COM port like the Non-PNP version. If you
are running
a computer with Windows 95, Windows should detect your new modem and will
prompt you
for an installation disk. Windows 95 will then help you complete the
installation.
If you are running either MS-DOS or Windows 3.1x, installation will probably
involve
running a setup utility provided with your modem. You will use this program
to select
your COM port and IRQ. Continue setting up your modem according to the
instruction
manual that came with your modem.
Once you have physically installed your modem and run the accompanying
software, you
can proceed to the next section, Making Sure You Have An AudioSpan Modem.
Making Sure You Have An AudioSpan Modem
Some users will find that the modems bundled with their computer systems may
not have
any obvious signs that indicate AudioSpan capabilities.
Here are a couple of ways for people running Windows 95, or MS-DOS to
determine whether
or not their modems are AudioSpan enabled:
    * Windows 95:
  1. Open the HyperTerminal folder by selecting Start, Programs,
Accessories, then
     HyperTerminal.
  2. Click on the HyperTerminal icon.
  3. Type a dummy name like "Temp" for this session. Click OK.
  4. Type a dummy phone number for this session. Click OK.
  5. Click on cancel and you should be in the modem command mode.
     You should be able to type "AT" and receive an "OK" message.
  6. Type "AT-SMS=2".
  7. If you receive an error message, you do not have an AudioSpan modem. If
the modem
     responds with an "OK", you do have an AudioSpan modem.
    * MS-DOS:
  1. Run any modem application software. One will typically be included with
your modem
     or computer package.
  2. Enter the modem command mode. You should be able to type "AT" and
receive an "OK"
     message.
  3. Type "AT-SMS=2".
  4. If you receive an error message, you do not have an AudioSpan modem. If
the modem
     responds with an "OK", you do have an AudioSpan modem.
 -----------------------------------------------------------------------
Windows 95
After installing your AudioSpan modem, open up your control panel and select
Modems to
ensure your modem is configured correctly. Your AudioSpan modem should be
listed in the
list of installed modems. If it is not listed, click the ADD button and
follow the
setup instructions. Select the AudioSpan modem if there is more than one
modem listed.
Next, select the Diagnostic tab and select the COM port that the AudioSpan
modem is
connected to. Then click the button labeled More Info. Windows 95 will then
attempt to
communicate with the modem. If your modem is configured correctly and is
operating, a
dialogue box will open up with Port Information and a Command/Response list.
If Windows
is unable to communicate with your modem, then you must resolve any
conflicts with
other devices by choosing System Properties in the control panel. Under
System
Properties, select the Device Manager tab to locate any conflicts between
devices.
If you determine that your modem is working correctly, making your AudioSpan
Modem work
with any software package will be fairly easy. Setting up software may
involve choosing
the correct AudioSpan modem from a list of modems provided by the software
vendor. The
modem setup for DataBeam's FarSite Lite, for example, includes
initialization strings
for Rockwell AudioSpan modems. Global Village's Global Transfer Lite package
includes a
check box to enable AudioSpan.
If your application uses your modem, but does not have a modem setup
procedure, then it
makes use of the modem profile in the control panel. Select your modem under
Modem
Properties, then choose Advance Connection Settings. Type the appropriate
AudioSpan
initialization string in the Extra Settings box. Click OK, then close the
control
panel. If your AudioSpan modem is not included in the list of modems for a
particular
software package, then it will be necessary to enter the appropriate
AudioSpan
initialization string when prompted.
If you are running a DOS program under Windows 95, refer to the MS-DOS
portion of this document.
MS-DOS
Configuring your DOS programs to enable AudioSpan is fairly easy. First, you
need to
find the COM port number, IRQ number, and speed of your modem. Consult the
Plug and
Play Issues section above to determine the settings of your modem, and
whether it is
Plug and Play compatible or not. You'll need to have the modem correctly
configured
with these parameters before trying to modify the initialization string to
enable
AudioSpan if you have a PNP modem.
In the future, most DOS programs will include all AudioSpan initialization
strings
(Handset, Headset, and Speakerphone) to choose from when configuring the
modem. Present
day and all older software packages will not have the string listed so
you'll need to
manually enter or edit one for your own setup.
Software packages that don't list an AudioSpan initialization string fall
under two
categories: those that have an internal modem profile and those that have an
external
modem profile.
Internal modem profiles are the types of software packages that let you
alter or create
initialization strings from within the program.
Find the section in your software documentation that refers to setting up a
multiplayer
game to get specific instructions on configuring your modem. Refer to the
General
Technical Notes section above for the initialization string that corresponds
to your
modem type and preferred operation mode.
External modem profiles are the types of software packages that have an
external file
the main program reads for its modem information.
Refer to your software documentation to find the name of this file. If the
software
does not already support AudioSpan, you will need to edit this file
manually. Follow
the format of the modems already listed and enter your AudioSpan entry.
Refer to the
General Technical Notes section above for the appropriate strings.
