I am new to this list, so please excuse me if I am repeating
things that already have been said.
(1) To the person who is having trouble with XMODEM on a VAX:
why not use Kermit? It is designed for file transfer
between dissimilar computers over a variety of types of
async connections. Your network may not be passing 8-bit
data and/or control characters through unaltered. Kermit
will work in such an environment.
(2) It is possible to disable the escape to command mode on
Hayes modems (i.e., +++). It is done by setting a value
greater than 127 into register S2, which holds the value
of the escape character. This is documented in the manual.
(3) Users of Hayes Smartmodem 2400s may want to check that
their modem is at a reasonably high ROM level. The
ATI command displays 24n, where n represents the ROM
revision level. A value of 7 or greater is best.
Very early modems had problems with excessive transmission
errors, even at 1200 bps. Other problems were fixed too.
