AT&H1 (Use CTS handshaking)

AT&R2 (Use RTS handshaking)

AT&S1 (Use DSR when ready for a call

ATS19=10 (10 minute inactivity timeout - optional)

ATS13=1 (Used to reset modem when DTR drops)

ATQ2 (Result codes on dialout only)

ATE0 (Turn off command echoing. At this time, you will no longer see characters echoed back)

AT&W0 (Store current settings in NVRAM)

Once the modem has been configured, don't forget to enable RTS and CTS handshaking for the port. This is what we set the modem to use for handshaking.

28.8Kb Modem Switches Switches should be set to factory defaults during programming. To prevent the modem from being reprogrammed inadvertently, Switch 8 can be changed from Down to Up AFTER the modem has been programmed and verified to operate properly. If using other communication programs than CCI TERM, then this switch will probably have to stay in the Down position at all times. Factory settings for those switches are as follows:

Switch 1234567890 should be UUDUDUUDUU,

where: U indicates UP and D indicates DOWN
