Test procedure
1) Operate the send machine first. The send machine will wait the "C" signal (send
request) reception from the reception machine.
The send machine will wait the send request signal about 30 seconds. When it is over
30 seconds, the time out error will be printed on the receipt.
2) Operate the reception machine. Then, the both machines are communicated each
others. This time first block data wait time is 5 seconds. The total resend request time
is 5 time.
3) During communication waiting time, the display will show the "-" brinking on the most
left side digit of segment display. When the data is OK, the reception/transmission
packet number will be displayed on the segment display.
NOTE1: To stop this opeartion, press any or trun off the mode key switch.

( Communication format is 8 bits, even parity, stop bit= 1bit fixed.)
