COM Port Select the COM port number connected to the cable. The initial value is

"COM1". "COM port" refers to a serial port, and the RS-232C interface is

used for communication. Only one COM port may be provided in some

personal computers.

Baud Rate Select the baud rate from "AUTO", "9600", "19200" and "38400" (some of

them may not be available in some personal computers). The default value

is "AUTO". "Baud rate" refers to the communication speed, and indicates the

number of bits which can be transferred in a second. As the baud rate value

becomes larger, communication is performed at a higher speed. Normally

"AUTO" should be selected.
