Using AT Commands
When using AT commands, the following criteria must be met:
Make sure the asynchronous DTE’s communication software is configured for 10-bit
character format (for example, 8 data bits, no parity, and 1 stop bit).
Make sure the DTE cable is attached to the DTE connector on the rear of the 391x Series
modem and to the correct serial communications port on the asynchronous DTE.
Configure the modem for Async Dial, Async Leased, or UNIX Dial as described earlier in
Using the DCP. To verify that the modem is connected and functioning properly, enter the
following:
TYPE: AT
PRESS: Return (Enter)
The screen displays OK.
If the modem does not return OK, refer to Appendix B, Troubleshooting.
NOTE
If the factory preset configuration is something other than Async
Dial, Async Leased, or UNIX Dial, you do not have AT command
control. To regain AT command control, select, via the DCP, the
Async Dial factory preset configuration as described in Using the
DCP
 on page 2-6.
