Ich habe meine Registrierkarte an Supra Deutschland geschickt.
Die Adresse ist:

Supra Deutschland GmbH
Rodderweg 8
5040 Bruehl

Tel.: 02232/22002
Fax : 02232/22003

Support-Box : 02232/22000    scheint im Moment aber down zu sein.

Ausserdem hat SUPRA USA eine Usenet-Adresse, siehe Text unten.

Meine Version ist die 1.200-C, angekuendigt ist die 1.2G ( siehe unten )

Selbstbrennen duerfte allerdings kaum moeglich sein, dem Vernehmen nach
verwendet der Rockwell Chipsatz ein (EP)ROM mit 55nS Zugriffszeit.
Solch ein Teil duerfte sehr schwer erhaeltlich sein.

Ansonsten sagte mir anlaesslich der Amiga 92 in Berlin ein Mitarbeiter am
Supra-Stand, dass die Eprom-Updates absichtlich nicht per DFUE verbreitet
werden. Die Vielzahl von Versionen bei Z***L wahr denen wohl ein
abschreckendes Beispiel.

>Wie ihr seht, eine ganze reihe von schwierigen fragen...  :-)

Gar nicht so schwierig. Anbei ein Text von SUPRA USA, den ich aus der
Support-Box eines Berliner Distributors von Supra gezogen habe :

Supra is doing the final beta testing on its latest rom for the SupraFaxModem
V32 and V32bis.  Provided that this testing is completed with no problems,
Supra will be ready to ship this rom to its current customers in a few weeks.
Many of the enhancements are unique to the Supra V32/V32bis modem and are not
available from other manufactures who are using Rockwell's v32/v32bis chipset
or other v32/v32bis modems/fax modems that are on the market.

The new rom is currently reved as 1.2G and will include the following
features:

	Enhances Busy Detection
	Fixes several Lock Display/Modem problems
	Improved Speed Renegotiation (Fall Back) upon bad line conditions
	Implements Fall Forward upon better line conditions
	Fixes Adaptive Answering (allows data/fax determination)
	Implements ECM	(Error Correction Mode)
		Note:  Must be supported by fax software
	Implements BFT mode (Binary File Transfer)
		Note:  Must be supported by fax/terminal software
	Fixes problem with DCD line turning off if modem configured with &C
	&Dx and &Cx settings are respected when in fax mode
	Fixes problem connecting with some fax machines
	Added S-Register S109
	Added S-Register S110=3

	Implements Silent Answer (allows voice/fax determination)
		Note:  Must be supported by fax software
	Implements Caller ID

Supra will be sending an upgrade offer to all registered owners.  This offer
will be for either a free ROM which has all of the above features, except
silent answer and caller ID, or for a charge of less than $30, a rom which
has all of the above features, including silent answer and caller ID.
Oversees customers will be able to get the roms from the overseas dealer that
sold it to them.  If they purchased the modem from a US dealer or Supra, they
will need to order the rom from Supra, but there will be a shipping and
handling charge.

You will be able to order either rom from Supra via its BBS.  We are
currently working on the software to allow this, plus to allow you to enter
your warranty card or change your warranty card online.  Once this is working,
it will be activated and you can immediately enter your order.	The quickest
way to order the rom will be via the BBS.  Until then, please do not contact
Supra to order either rom.

The above information is subject to change or modification.  At this time,
this is all that is known.  As soon as costs and other information is known,
we will let you know via the Supra BBS.


UPCOMMING FEATURES AND NEW PRODUCTS:

The following features and new products are being worked on.  We do not have
any information on dates, technical information, upgrade costs, or product
cost. As soon as we have the information, we will post it on our BBS.

	Internal version
	Certifiable International version
	MNP10
	V23
	Voice digitization in modem
	Voice software
	DTMF encoding/decoding


MORE INDEPTH INFORMATION ON 1.2G ENHANCEMENTS


Enhances Busy Detection
	Some people had several different problems with busy detection.  All
	calls would return BUSY or only certain calls would return busy.  All
	known problems have been fixed. This problem only happened to a small
	percentage of users.

Fixes several Lockisplay/Modem problems
	The Supra v32bis modem is running several different processors and
	tasks at one time. If the right timing sequence or events happen,
	the modem could lockup.  The only way to fix the problem was to
	power cycle the modem.	This problem only happened to a small
	percentage of users.

Improved Speed Renegotiation (Fall Back) upon bad line conditions
	The 1.2C rom was our first rom to implement this feature.  We have
	continued to improve our code to better handle bad line conditions,
	especially at connect time.

Implements Fall Forward upon better line coditions
	Once the phone line conditions improve, the modem can initiate a step
	up in baud.

Fixes Adaptive Answering (allows data/fax determination)
	A mode which allows the modem to connect with either a fax or a data
	modem.	Once it makes the connection, it will return a result code
	indicating which one it connected with.  It is then the software's
	responsibility to route the call to the proper program.  Some "front
	door" software for BBSes and terminal programs have this ability.
	"Front door" software has control of the serial port and waits for an
	incoming call.	When it receives a call, it may present a prompt to
	the user asking which program they want to run, or based upon the
	modems result code decide which program is to be run.  (Thus it
	functions as a call router.) The "front door" software then wakes up
	or runs the correct program, which than takes over control of the
	serial port and thus the modem.  When the call is ended, the program
	quits or shuts down and lets the "front door" regain control of the
	serial port/modem.

	AT +FCLASS=0
	AT +FAA=1 (if using class 2) or +FAE=1 (if using class 1)
	AT S0=(1-255)  or ATA

	Result Codes:  CONNECT XX if data call
	FAX if fax call

	NOTE:  This sequence must be sent before every answer

Implements ECM	(Error Correction Mode)
	Allows the fax software to resend a block of information if it is not received
	correctly by the other modem.  This feature MUST be supported by the fax
	software in order to be used.

Implements BFT mode (Binary File Transfer)
	Allows the user to send a file to another fax modem as if it were a
	fax instead of a file.	This feature MUST be supported by the fax
	software in order to be used. This allows the user to use the fax
	software to send the file instead of using a terminal program.

Fixes problem with DCD line turning off if modem configured with &C
	If the modem was configured with the &C, especially during a
	disconnect, the modem would toggle DCD line.  This problem only
	affected a small percentage of users, generally those running BBSes
	on the Apple II.

&Dx and &Cx settings are respected when in fax mode
	The CCITT TR29.2 committee has not defined how the modem should
	react to the &D and &C settings when in class 2 fax mode.  While the
	committee has not defined this, there is a strong sentiment for
	respecting the &D and &C settings as it is handled in class 1 and
	when the modem is in data mode.  This also allows the modems to work
	better under fax mode in the Unix enviorment.

Fixes problem connecting with some fax machines
	The 1.2C roms had a few problems making connections to some fax
	machines.  The fax machine used a slightly different tone when
	answering.  This rsulted in the two machines toning back and forth,
	not making a connection and then eventually hang up. This problem
	only happened to a small percentage of users.


Added S-Register S109
	Controls speeds available for V.32bis carrier handshake, or the
	carrier rate to negotiate error correction, if S-Register S110=3.

	Decimal Value	Explanation
		1	reserved
		2	4800 bps
		4	7200 bps
		8	9600 bps
		16	12000 bps
		32	14400 bps
		64	reserved
		128	reserved

Added S-Register S110=3

	V.32bis standard negotiates carrier speed at 4800 baud then jumps to
	the agreed carrier speed to negotiate error correction/data
	compression.  On noisy lines this can cause various connection
	problems.  Supra's solution is to set S-Register S110 to 3.  This
	causes the modems to connect at the slowest possible V.32 or V.32bis
	speed.	Once this is done, as long as the line is clean enough, the
	modems will up-shift to the next possible carrier rate.

	The slowest possible carrier speed can be limited by the use of
      S-register S109.

NOTE:	Some modems can only up-shift a few times and then they will lose the
	connection  (especially Supra V.32 and V.32bis with ROMs < 1.2C).
	The solution is to change S-Register S109 so that it does not need
	to up-shift as many times.

NOTE:  This only works when the modem is originating the call.

Implements Silent Answer (allows voice/fax determination)
	When the phone rings, the modem will start monitoring the telephone
	line after the 2nd ring.  If it detects a fax tone, it will do one
	of two things:

	1.	If S-Register S0 - 0, the modem will immediately answer the
		phone and attempt a fax connection.

	2.	If S-Register S0 = 0, the modem will quickly issue up to 9
		RINGS messages, expecting the fax software to issue an ATA.

	This eliminates the need for a $150 voice/fax black box.

NOTE:	DO NOT plug the answering machine into the telephone jack on the back
	of the modem.  The modem should be plugged into the answering machine.
	This also also works if a telephone is in the circuit before the
	faxmodem.

NOTE:	This mode must be supported by the fax software.

Implements Caller ID

	This is a feature is only available in some areas of the country.
	In between the 1st and the 2nd ring, the phone company will send
	information on who is calling you.  If you ere in terminal mode and
	had told the modem to answer on the 3rd ring, you would see:

		RING

		DATE = 0321
		TIME = 1405
		NMBR = 5039672400
		NAME = SUPRA CORPORATION

		RING

		CONNECT 19200

	To enable CALLER ID:

		AT#CID=1	Enables Caller ID in formatted format
		AT#CID=2	Enables Caller ID in unformatted format
				(ASCII printable hex numbers)
		AT#CID=0	Disables Caller ID


In addition to the enhancements and corrections noted above, Supra's new 1.2G
ROM release also includes modifications that were implemented in the previous
1.2C ROM release.  They are as follows:

%G0	disables Rate Renegotiation on V.32bis

%G1	enables Rate Renegotiation on V.32bis
	enables Rate Renegotiation and Retrain on V.32

%E	has not changed, but if both %G1 and %E1 are set, then the modem will
	Rate Renegotiate during a Retrain.  This is also the only way the V.32
	modem can Rate Renegotiate.

AT&F1 and AT&F2 defaults now include %G1

S-Register S110:

	0	causes connect at V.32 only
	1	enable V.32bis on V.32bis modems
	2	enable V.32bis and automatic rate renegotiation.


Fixed several problems on the fax side of the modem
