Checking The Serial Port Settings; Using The Ext Kb Port - Epson ActionNote 4SLC/33 User Manual

Checking the Serial Port Settings

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.

Using the EXT KB Port

You can use the EXT KB port to connect the Logitech trackball or
any PS/2-compatible pointing device.
You can also connect the mouse/keyboard adapter to this port.
This adapter has two ports, which allow you to connect both a
pointing device and an external keyboard at the same time. You
can connect a PS/2-compatible keyboard to this adapter; it does
not support AT
