Epson 4SLC2-50 User Manual

The 

COM 1 

and 

COM 2 

ports are capable of sending and receiving

data at a 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.

You can use the 

EXT KB 

port to connect the trackball or any

PS/2-compatible pointing device. See Chapter 1 for detailed
instructions.

You can also connect the mouse/keyboard adapter to this port. If
you use the adapter, you can connect both a pointing device and
an external keyboard at the same time. You can connect a
PS/2-compatible keyboard to this adapter, but it does not support
AT

®

-type keyboards.
