Settings Key

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.

Value : type Description

DccRetries Default setting is 3. The number of times to retry direct cable connection.
DialBilling Default setting is <$>. Specifies whether the modem supports the '$' wait for credit card prompt tone (bong). A value of 0 indicates that this capability is not supported. If it is not supported, Unimodem will insert multiple commas to cause the modem to wait. If this registry value is not present, support for '$' is assumed.
DialPrefix Default setting is D. Prefix for any dial command.
DialSuffix Default setting is <;>. Extends a dialing string across multiple commands.
