USR Sportster ISDN 128

The US Robotics Sportster 128 is an internal ISA card that appears to DOS, Windows, and NT as a dialup adapter. It includes one POTS jack, and requires a special ring adapter in order to send ringing current to attached devices.

Some minor configuration problems (IRQ and other settings) were found, the setup software mistook software port settings to be a problem contacting the telco switch.
