[comp.dcom.modems] Trouble with MNP class 5 modem & VT100 clone

tpc@bnr-fos.UUCP (Tom Chmara) (06/21/89)

I've been having trouble with a dialup connection I've been trialing.
I have an old Volker-Craig VC2100 terminal (dating from my grad school
days) which acts a lot like a VT102.  However, some of the delays
(cursor movement, etc) seem to take a bit longer.  No problem, says I,
hacking the termcap, we'll get that fixed.
	But NO!  I'm still losing characters (especially in vi, or
when refreshing a screen); the cursor will not be placed in the right
place and/or some characters on the line will not be present.  The
termcap LOOKS right, the modem is set to handle XON-XOFF...what have
I missed?  My uneasy feeling is that the modem is doing compression,
and those nice time delays that UNIX puts in are being lost in transit.
The system I'm using is:
	Sun 3/60 running SunOS 4.0.1
	Microcom AX/2400c modem (2400bps)
	VC2100 terminal (VT102 clone)
	dialup port is a CISCO terminal adapter
Anyone able to help?
	Thanks...
