Checking the Serial Port Settings

The 1 port is capable of sending and receiving data at a
COM
variety of speeds and with many different protocols. This
means you need to configure the port to match the signals of
the serial device. As a general rule, choose the highest speed
(baud rate) and the protocol that provides the best error
detection.
Check the documentation that came with your serial device to
see if you need to adjust any of its settings.
Note
If your application program cannot send printer output
directly to the serial port, you can use the MS-DOS MODE
command to redirect the output. You can even tell the
computer to redirect printer and serial port settings
automatically if you place the appropriate MODE
commands in your AUTOEXEC.BAT file. See your MS-DOS
manual for instructions.
