U.S. Robotics I-modem Command Reference
Modes of Operation • Page 2-2
Depending on how bit 0 of S-register 14 is set, the I-modem will either revert to
Command mode or hang up when you send the escape code. To be able to change
operating modes without losing connections, make sure bit 0 of S-register 14 is
OFF:
ATS14.0=0&W <Enter>
Once the I-modem is set to revert to Command mode, when you type three pluses
as described below, the I-modem will enter Command mode.
1. Wait one second after sending the last item of data.
2. Type +++ (Do not type the AT preÞx or press Enter.)
3. Wait one second before typing any data.
