IBM SC30-3681-08 Modem strings, Command strings sent to the attached modem, Initialization string

Con®guring V.34

set this parameter to 0, the router waits for the modem to respond to DTR with the CTS (Clear to Send) signal before it issues commands.

Connect

Number of seconds allowed for a call to be established. If this parameter is set to 0, the modem controls the connection establishment timeout.

Disconnect

After the routers drops DTR it waits this amount of time before it initiates further calls. If you set this parameter to 0, the router waits for the modem to respond to the DTR drop by dropping CTS and DSR before it initiates the next call.

Modem strings:

Command strings sent to the attached modem.

Initialization string

This is the last AT command string sent to the modem during initialization (before a call is accepted or attempted). A default string is provided which should work for most modems.

Speed (bps)

This is the DTE speed. The default should work for most modems, but you may need to set the speed lower to operate properly or higher to achieve maximum data speeds supported by the modem.

Set

Use the set command to con®gure local addresses, timeouts and delays for calls, retries and timeouts for non-responding addresses, and the HDLC cable type.

command-delay-timeout # of milliseconds

After the router turns on DTR (Data Terminal Ready), it waits this amount of time before it initiates or answers a call. If you set this parameter to 0, the router waits for the modem to respond to DTR with the CTS (Clear to Send) signal before it issues commands. The range is 0 to 65535 milliseconds, and the default is 0.

connect-timeout # of seconds

Sets the number of seconds allowed for a call to be established. The range is 0 to 65535 seconds, and the default is 60. If you set this parameter to 0, the modem controls the connection timeout. You should initially set this parameter to 0 and then use ELS event V34B.027 to ®nd out how long it
