(serial port)
Switch 1 tells the computer how to access the built-in serial
port, as follows:
The built-in serial port functions as either the primary or
secondary serial port. You may decide to install an option
card that has its own serial port. Make sure you set the DIP
switch or jumper on the option card as well as the DIP
switch on the Apex so there is no conflict between the
built-in serial port and the added card.
If you install an option card that has only a serial port, you
must set
the DIP switches to designate this as the secon-
dary port and leave the built-in port as the primary port.
MS-DOS needs to know the number of serial ports you
have. If MS-DOS searches the system for a serial port and
finds only one, it names it COM1:. If it finds two serial
ports, it names the primary port COM1: and the secondary
port COM2:.
