The Settings key contains commands for configuring various modem settings. The following table shows the registry settings for the HKEY_LOCAL_MACHINE\Drivers\PCMCIA\CompanyX-GenericModem-1234\Unimodem\Settings key.

DialSuffix Default setting is <;>. Extends a dialing string across multiple commands.
