"Pauses" while cu'ing between two SCO systems with Intel 9600EX V.32

[Mark J. Bailey [ADMIN]]

Hi,

Well, all the hype about V.32/V.42/and V.42bis finally got me to cave in and
order some V.32 modems.  I took advantage (I guess?!) of the Intel 9600EX 
Sysop's Special Offer (I have a bbs).  While I do not care to debate the 
merits of that program, I do have a question.  I have an SCO Xenix system 
at my home that I call into my SCO ODT 1.1 system every night.  I ordered
two of the Intel modems and put one at home, and one on the ODT system.  
I configured the ODT system for a getty of 19200 (locked) between the computer
and the modem.  I set CTSFLOW in the final state of my gettydefs entry:

19200V # B19200 IGNPAR ICANON IXON IXANY OPOST HUPCL ECHO ECHOE ECHOK CS8 CREAD # B19200 IGNPAR ICANON IXON IXANY CTSFLOW OPOST CS8 HUPCL ECHO ECHOE ECHOK CREAD #Intel 9600EX (tty1A)\r\nmjbtn!login: # 19200V

I then set the modem's two non-volatile memory storage registers up as:

STORED PROFILE 1:
B1 E0 L2 M1 T Q0 V1 X4 Y0 &C1 &D2 &G0 &J0 &L0 &P0 &Q0 &R0 &S0 &X0
\A3 %A013 \C2 %C1 %E1 \G0 \J0 \K5 \N3 \Q2 \T00 \V2 \X1 -J1 "H3 "O250
S00:002 S01:000 S02:043 S03:013 S04:010 S05:008 S06:002 S07:017
S08:002 S09:006 S10:014 S11:070 S12:050 S18:000 S25:005 S26:001

Issue the command 'AT&W1'

STORED PROFILE 0:
B1 E0 L2 M1 T Q0 V1 X4 Y0 &C1 &D2 &G0 &J0 &L0 &P0 &Q0 &R0 &S0 &X0
\A3 %A013 \C2 %C1 %E1 \G0 \J0 \K5 \N3 \Q2 \T00 \V2 \X1 -J1 "H3 "O250
S00:000 S01:000 S02:043 S03:013 S04:010 S05:008 S06:002 S07:030
S08:002 S09:006 S10:014 S11:070 S12:050 S18:000 S25:005 S26:001

My Dialers script simply switches the modem between the two states (1 for
dialin and 0 for dialout):

#
#  Intel 9600EX
#
intel9600 =,-,	"" ATZ0\r\c OK\r \pATDT\T\r\c CONNECT
#
#  and afterwards reinitialise to dialin mode
#
&intel9600 =,-,	"" +++\dATZ1\r\c OK\r \pATQ1\r\c

A Devices entry of:

ACU tty1A - 300-19200 intel9600

FASTACU tty1A - 300-19200 intel9600

direct tty1a - 300-19200 direct

OK, now, everything appears to work great at first.  The \X1 in the modem
setup says to "Pass XON/OFF codes through to remote modem".  \G0 disable 
modem-to-modem XON/XOFF flow control.  \Q2 sets up Unidirectional RTS/CTS
(since SCO won't work with Bi-Directional RTS/CTS flow above 9600).  

When I first connect using high speed, evevything is fine.  I get the V.32
tones (etc) and it connects and I get a CONNECT 9600/REL (and it *IS* Fast!).
I login to the system, and almost everytime, as it is displaying the first
screen of login messages, it will just freeze in the middle of a line and
sit there and will only resume if you hit ENTER!?!?!  Again, I am running
19200 from CPU to modem at the remote end.  I am calling via cu at 19200 
to the modem here on my end.  Someone (not sure if my end or remote) told
the system to pause, then never got the go message to it again.  Maybe it is
something else?  

But the *really* weird thing is that when I boot my system up under MSDOS, and
then load Procomm Plus, I can call with all other things remaining the same, 
and it seems to work fine.  It has something to do with calling under Xenix
and maybe even under cu (although we tried ecu and pcomm, and they both had
freezes eventually).  Also, freezes occur suring uucico transfers.  On large
files, it will chug merrily along for a while then stop for no reason, then 
after about a 10 second pause (enough for an alarm - I think), it picks up
again.  This is a big downer here.

Anyway, I thought that I would pose this to the net while trying some other 
settings, and maybe, just maybe, I might get these things to work.  It is 
kind of frustrating to have such a truely fast link and have this get in the
way.  :-)

Any and all input and suggestions would be greatly appreciated!

Thank you,

Mark.
