Start Channel Number Option
The S)tart Channel # option is used to specify the beginning channel
number for all IPC-1600 provided ports. Each IPC-1600 port in the system is
assigned a number that distinguishes it from the other ports in the system.
These channel numbers are used by the driver and INT 14h calls. Selecting
the starting channel number specifies the range of numbers the
communications ports will use. The standard MS-DOS COM1 and COM2
ports use channel numbers 0 and 1. The default starting channel number for
the first IPC-1600 port is 4.
The following screen display shows how to specify the starting channel
number.
