HM> My lecture notes from last semester would seem to agree with you. :-)

Splendid. BTW reading your prev message and the bits you quoted, either I
made a silly mistake or Ian did (or both).

[a little later].. no that was a quote from Ian. Now everything makes sense.

HM> RS232 -12V for a 1, +12 for a 0? The lecture notes certainly show 0

Sorry bud, I just program here. Voltages are hardware, I tell the engineers
to worry about it (unless we're talking purely digital circuits with nary
an inductor in sight).
