By specifying a value 8 in S29, the user causes the remote modem to implicitly assume that a V.110 connection is to be established. This command indicates that an ISDN call is being requested, and when used with the S29=8 command, results in modem code issuing a ISDN_DIALSTRING (0x45) request being made to the host.
After entering the S29=8 command, you can enter the desired user rate if different from the default value of 9600 bps. This command takes the form: S57=speed. For supported rates, see the “Restrictions” section. For example:
S57=19200
