connected to the target port. The COM port test checks DTR, DSR, CTS, RTS, TXD, and RXD
signals.
When the test finishes normally,
OK
is displayed in the message area of the screen. When the
test fails, an error message is displayed.

LPT1 loop-back
The LPT1 signal lines are tested. Because transmission and reception are performed through
a single target port, the loop-back connector needs to be connected to the target port. The
LPT1 port test checks STROBE, ACK, DATA0, BUSY, AUTO FEED, PAPER EMPTY, ERR,
INIT, SELECT IN, and SELECT signals. In the loop-back test, the data line test is not
executed. Data line check must be made through the LPT1 print test.
