Tools -> Connect Modem - Configure Remote Modem Command

From the Configure remote modem command dialog, you can use the name of the remote modem to access and configure a remote modem. You can select the check box to accept the default settings for the modem commands, or you can choose not to use the defaults and to edit the individual commands. The "Additional" field provides the opportunity to enter other modem commands. Separate each one with a blank if you add additional commands.

The commands are all standard commands. Refer to the documentation provided with your modem for specific command syntax.
