U.S. Robotics I-modem Command Reference

Analog Synchronous Applications • Page 16-14

Note Data Terminal Ready (DTR) override must be OFF when using the I-

modem in online synchronous mode. Use &D1 or &D2. See Chapter 6,

Controlling EIA-232 Signaling.

ConÞguring the I-modem

1. If your communications software isn't running, load the program and start T

erminal

mode (see your software userÕs guide for instructions).

2. Send AT&F0B0&X0 <Enter>.

The device you are calling should also be set to the equivalent of B0, which tells the I-

modem to use the V.25 answer sequence, and &X0, which identiÞes the I-modem as the

source of synchronous timing signals.

3. Set the connection rate to be used (between the I-modem and the remote communica-

tions device) when the I-modem is online.

First try a variable connection rate of &N0. If that doesn't work, try a Þxed connection

rate of &N6 (9600 bps) or &N3 (2400 bps).

&N0 Variable (default) &N8 14.4 Kbps

&N1 Reserved &N9 16.8 Kbps

&N2 1200 bps &N10 19.2 Kbps
