Method: Asynchronous
Speed: 9600bps (Subtests 01 to 05)
Data: 8 bits and one parity bit (EVEN)
Data pattern: 20h to 7Eh
The following message appears at the bottom of the screen when Subtests 01, 03, 04, or 05
are selected:
Channel#1 = XXXXh
Channel#2 = XXXXh
Channel#3 = XXXXh
Select the Channel number (1/2/3)
The serial I/O port address is specified by the XXXXh number. Select the serial port channel
number. Press Enter to start the subtest.
