Anyone ever try connecting at 1200bps in Linux? I've got a USR 56K
Faxmodem which is meant to connect to another (same) modem and I have to
connect at this speed due to the (NT) port settings on the remote side,
but the modem handshake always fails at this speed.
The modem handshake works at slightly higher speeds (4800bps to
~57600bps) but that is no good for tx/rx'ing data to the remote server
as it insists at talking at the speed of treacle/1200bps.
Note Minicom fails to handshake at 1200bps, but HyperTerm in Windows
I am doing a ATZ3 to reset the modem then I send this init string:
USR said to set S15=128 (disables v.42))
But the S15=128 just makes the handshake lockup instead of just giving
btw this is a bank's system I am connecting to so reconfiguring their

It sounds like the flow control is set to Xon/Xoff rather than hardware.

I think that the AT command for hardware flow control is &E4 though this
