Subject: Modem NVRAM: Reset by O/S Class codes?
From: kmcvay@oneb.wimsey.bc.ca (Ken Mcvay)
Date: Thu, 16 Apr 92 02:26:13 GMT
Followup-To: comp.dcom.modems
Organization: The Old Frog's Almanac, Vancouver Island
Keywords: THEOS 

The modems: ATI 9600etc/e and USR HST v32/v32bis
The o/s:    THEOS 386 v3.1
cpu's:	    Altos 1000 & various generic 386's

The players: Me, mild-mannered modem fixer, and...
	     everybody else :-(

The problem: The modems are programmed for optimized performance, and
will accept inbound logons at any speed from 300 baud to their limits.
After setting the modems up and writing the settings to NVRAM, the
modems will perform for a varying period of time without flaw.

Then they quit working. 
Then I yell at everyone in the office about reprogramming the modems,
and they all swear they didn't. In all the years I've played with
HST's and other modems with NVRAM, I've _never_ seen one reprogram
itself - at least not in DOS or UNIX.... THEOS? Well........

THEOS ports are started with designated 'class codes.' Unlike my XENIX
system, which doesn't much care what you are emulating when you call,
THEOS is hard-wired in a boot-config file (system.theos386.config).
The ports that are giving me trouble (auto-reprogramming modems) are
all running CLASS 90.

CLASS 90 is PCTERM, which uses scancodes. Scancodes send the modems
out to lunch. To get around this, we turn the modems OFF whenever the
machine is reset, and then turn them back ON after the system is back
up, and the ports re-started. Once THEOS has started the port, it
doesn't send anything to the modem until it's actually in use, at
which point the modems become transparent.

To STOP a THEOS port, you simply tell THEOS to "stop <user #>" and it
usually does it instantly. On CLASS 90 ports, however, since stopping
a port makes THEOS send "This terminal has been stopped" out the port,
it takes a minute or so for THEOS to give up -  i.e. it sends the
STOPPED code to the modem, which, receiving scancode, immediately goes
south for the summer and turns brain-dead... THEOS gives up and stops
the port anyway.

I have seen changes in NVRAM ranging from two modems on the same host
changing &D3 to &D2 (which made me _very_ suspicious :-)) to going
completely wierd, and setting every register to zero. 

On both the ATI's and the USR's, reprogramming has never been a
problem.

The question: Given that THEOS sends scancode data to the C90 ports at
boot, and assuming multiple hardware resets without the modems being
turned off and back on, is it possible that the scancode data could
reset NVRAM and WRITE the results to the EPROM?

Film at eleven :-)

Any advice if My PC has one 8250B on the motherboard that cannot be
disabled only switched to either COM1 or COM2, so if I added a board with
a 16550 as the second port it would probably have to be COM3 and some
software doesn't like to talk to COM3.

I have heard of boards that have a 16550 installed but they are usually
over priced.

This doesn't matter right now but it may when I get a high speed modem.

I borrowed a Multi-Tech v.32 modem from a friend and am having some trouble
configuring it.  I am using an Amiga 3000 and JR-Comm 1.02 as my terminal.
What puzzles me is that uploads don't work correctly, yet downloads do.  I
get a request to re-send a block of data (I use Zmodem) about every 8k, 
and it has to back up and re-send the block, sometimes several times.
I have fiddled with RTS and XON/XOFF and am not sure about the RS-232 rate
speed and modem speed (this modem has settings for both).  If you have this
modem and have no troubles, please send me your config (If I have too, I'll
hook it up to my IBM).  If you have this modem and the amiga -PLEASE send
me the config and any notes on Workbench or Jrcomm settings.

Organization: People-Net [pnet51], Minneapolis, MN.

I need help configuring a MultiTech 932BA 9600 BPS external modem to
Consensys Unix System V Release 4.0.  I have the modem connected to COM1
(although I have tried COM2 as well) with a standard serial cable.  This
configuration works fine under MS-DOS 5.0...so I expect that the hardware is
configured properly.  When trying a cu or a uutry, the DTR light comes on, but
the modem does not respond beyound that point.  The alarm signal kicks in and
the session times out.  I have also attempted to write some C code to control
the modem, if I do an open without specifying O_NDELAY, the open hangs until I
break it (DTR does get asserted by this open).  If I do the open with O_NDELAY
set, the open continues beyond that point, DTR becomes asserted, but the modem
still does not respond.  Any help on this issue?  I have tried all of the
devices for this port to no avail (hardware and software flow control
variations).  Any help would be much appreciated.  Thanks in advance.
Bill.

OK.  (a) There are more products involved than just the T3000SA, and (b)
serial numbers used for LP may be used again for LPA.  Kinda like a more

Ok.
I see plenty of articles talking about the ZyXEL U1496 modem series.
Yet though I've asked twice, I've only gotten one reply to my
questions about it.  I'll try again...

(1) WHERE can they be bought, and HOW much?

(2) Can they initiate and respond to retrains both faster and slower?

(3) Is the FAX command set documented?

Please send me some answers, ZyXEL folks...I know you're out there! :-)

Please email...I'll summarize to the net.

You are confusing Groups with Class.  Groups 3 is a standard for communication
with FAX modems (and is also backwards compatable with Group 2 and 1 but
nobody has these anymore). Class 1 and 2 are standards for the computer to
communicate with the FAX modem (you know, the FAX "AT" commands).

I often travel outside the US and take my notebook PC.  I need to

a solution when I find pulse dial in my hotel or the office I'm working
in.  How can I manually dial a number (including possible USA Direct

without dialing?   Since my PC only has one jack, I also need to unplug

I would appreciate any and all help, since I will soon be facing this

Hello!
I own a ZyXEL U-1496E and wanted to give a little bug report here...
Ah,yes I own ROM version 4.05T.

BUGS: 1 - no pulse dialing possible with extension phone picked up (falls back
          to voice ,while pulsing = dialtone after dialing)
      2 - doesn't recognise BUSY when dialing by hand/(through to another LD
          carrier - maybe) and connecting via ATD  ,but does it if <fake> dialstring
          is there (maybe a ATD, ).
      3 - probs with the modem adjusting the volume ,e.g. VERY low (AT L3)
          volume,so you don't hear the carrier,almost...then a FULL VOLUME local
          BUSY beeping in! (seems to be related with 2)
      4 - RING 's while dialing pulse over the ext. phone
      5 - RING loudness (it has a bell!) could not set to 'off' ,but the manual
          tells you so.
      6 - after (4),modem results an ERROR several times when issueing other
          commands then AT  alone,f.ex. ATZ which results in an ERROR up to 5 times!
      7 - Loudspeaker is OFF when ATH1 is issued (I want a dialtone,there!)
      8 - can't issue a BREAK from command mode,so after a Zyxel disconnects,
          all v32bis modems on the other side will try to retrain for some 20-40 secs
          before reporting in the known way....(remote Zyxel's,too,of course)

Needless to say ,I'm very happy with the modem. I have never owned such a nice
plug-in-and-play solution in telecomm's ever!!
Just issue AT&F or ATZ and you are set with most Amiga's/PC's/Atari's.
Just minor things in the factory settings have been changed so far,
as loudness/ringer loudness,and DCD always high,because my serial hw is somehow buggy...

bye,Kai.

Yeah, and this doesn't make their life any easier (:-).

Well, of course ZyXEL hasn't implemented  SP 2388-B (yet :-).

But I can hardly blame them for that. After all - how many times
should they re-implement the same thing? (:-) What if 2388-B
will have the same fate as 2388-A?

This is hardly a fault with the modem.  Take an extension phone off
hook, and attempt to pulse-dial from another phone.  It just doesn't
work.  That's the nature of the beast.

I use a dual standard in both HST and v.32bis at 14400 with other modems and
always get better results with Ymodem-G, maybe you should run some more

I think the point Greg is trying to make here is being missed.  I
believe he's talking about non-16550-aware software benefiting by
having the 16550 FIFOs enabled *by some other software.*  This is, in
fact, what I used to do on my old 286 UNIX system.  The drivers knew
nothing about the 550, but I would enable the FIFOs at boot time, and
saw a 40-50 cps improvement in throughput on a TB+ at 9600 bps.  The
async driver's interrupt handler read data from the UART as long as
there was data to be read.

Ah, but how much is it?  Since it hadn't been announced, it's not

What's the LPA price for a WorldBlazer?  $699?

Uh, I thought Greg already did.  Somehow it strikes me as unlikely that
Telebit would develop TWO firmware upgrades for the engine that is in the
T3000 and then only announce one of them.  Development isn't exactly cheap, 
you know.  (Besides, if there is a modem available with Turbo-PEP, who's gonna 
want the plain-vanilla-PEP one unless there is a mondo price difference?)  

Marty Likier, are you out there?  Can you give these non-believers the 
'official' word, since you're in marketing?  (Greg, for all his brilliance, 
assistance, and good information on Telebit, is 'only' in Tech Support.
Gee, Greg, if you're lucky you'll end up being the next Chuq!)
