SUMMARY
To configure a Hayes Optima modem to communicate with an SNA Server SDLC link service in a switched line environment, the following commands must be sent to the modem. These commands will set the modem for synchronous mode and store a phone number in the modem. When SNA Server is started, this will cause the modem to automatically dial the stored number.

Hyperterminal can be used to send the commands to the modem while the modem is still connected to the SDLC card in the computer. It is not necessary to move the cable to a serial port to configure the modem.

Send the following strings to the modem:

AT&F&Y

AT&Z0=Txxx-xxxx

AT&Q2&C1&D2&S1

ATE0Q1&W

Replace xxx-xxxx with the phone number you want the modem to dial.

NOTE: These settings will overwrite any previously stored startup parameters.



MORE INFORMATION
Here is the meaning of the required modem commands. For additional information, refer to the documentation accompanying your modem.    &F              Set to factory defaults &Y             Select stored profile as active profile &Z0=Txxx-xxxx  Tone mode, autodial &Q2            Synchronous mode &C1            Received Line Signal Detector (RLSD) state &D2            Data Terminal Ready (DTR) behavior &S1            Data Set Ready (DSR) turned ON at handshake E0             Echo Off Q1             Result codes disabled &W             Store active profile In SNA Server's configuration for the link service, set the line type for Switched: Modem-Stored Number.
