It's a "text lite mm500", made in
Ireland apparently for a german
company (www.textlite.de I think). Seems to want about 6V 1A.
The serial port is a 1/8" phono-stereo jack so I'm tempted
to try the cord for my digital cam on it, a better than 1:6 chance of
the connections being right.
Well, 'sleeve' is going to be ground, so assuming that tip and ring are
TxD and RxD, you've got a 50% chance of them being the right way round.
One word of warning, though. Does it contain RS232 level shifters, or are
the signals on the socket at TTL levels? If the latter, then connecting
an RS232 port directly will kill some chips!
