7Managing Serial
Driver COM Ports
Overview
The Serial driver for the communications controller is
automatically installed with the Base driver software. The
Serial driver emulates COM ports (serial ports) connected to
the digital modems on the board, which includes from 12 to 30
digital modems. The Serial driver emulates COM ports on
ISDN B channels. It enables systems to use the board’s
modems simultaneously with legacy applications that require
COM port communications, such as fax software, remote
applications control software, and BBS access
(Hyperterminal) software.
The Serial driver emulates COM port connections for up to
four 5536 communications controllers, provided that sufficient
memory and CPU resources are available.
This chapter explains how to do the following Serial driver
COM port management tasks:
• Set up Serial driver COM ports
• Declare Serial driver modems in Windows NT
• Verify Serial driver COM ports
