this is probably related to the OmniGo's serial port not using/supplying all the
signals which are normally supposed to be present on a 9-pin serial connector.
This is a message I picked up on comp.os.geos some days ago...

Here is some important information about the OmniGo 100
serial port's hardware flow control lines.
The only pins connected are -
Tx (transmit)
Rx (receive)
RTS (request to send)
CTS (clear to send)
The following pins are not connected and can not be used
for flow control -
DTR (data terminal ready)
DSR (data set ready)
RI (ring)
CD (carrier detect)

The main problem in your case is probably the missing DTR line which is required
to be "on" by some modems in order for them to dial out. I have no external
modem here which is affected by the problem, but apparently including AT&D0 in
the init string of the comm program is said to cure the problem, forcing the
modem to ignore DTR completely.
