SERIAL PORT LOOPBACK DIAGNOSTIC TESTING RULES
When the diagnostic asserts RTS (output) it then tests for the presence
of CTS and Ring Indicator (input). If CTS and RI are detected the RTS driver and
CTS/RI receivers are considered operational. When DTR is asserted (output) the
diagnostic tests for the presence of CD and DSR (input). If CD/DSR are detected
the DTR driver and CD/DSR receivers are considered operational. Data is Xmitted
and received on the data lines and the data is compared in the diagnostic buffer.
If any status's are not detected an error message is displayed.

port with input and output capabilities often used with external tape drives and
accessory devices. If pins 31 or 32 are grounded on a cable the printer will fail to
come ready when attached to the PC. This is common on low cost parallel printer cables.

NOTE!! This pinout is from a ECS P5VX-B MB with PS2 mouse option.
Not the same as the one on file.
Best way to find out is
Power OFF PC
Meter resistance between +5V power lead and pins on connector
(find +5V pin)
Meter resistance between GND power lead and pins on connector
(find GND pin)
Wire up pins 3 and 4 of Mini-Din connector to known +5V and GND
Try pins 1 and 5 of Mini-Din using remaining pins and swap them
round if it does not work, until you get a working combination.
Reset processor (or power cycle) between tries.
Once +5V and more importantly GND are wired correctly trying other
combinations will not damage working mouse port and mouse.

The one piece of PC cabling info I couldn't find on
http://stason.org/TULARC/pc/pc_pinout.html was the
connections/pinouts for a laptop external Mouse/Keyboard Y splitter
cable. I've since found it/worked it out, and if you would like to
add it to your page (where far more people will be able to find it
than on mine) the info is as follows:-
