[WT-support] PTT keying

[Stewart GM4AFF]

Apologies if this has been asked before. Is there a circuit for and an
explanation of the PTT functionality built into WinTest for use with COM and
LPT ports? Ideally I would like a little circuit not just for keying the
(LPT pin 17) CW (as in the Wiki) but also showing how the rig PTT could be
closed by (LPT) pin 16. Also interested in how this functionality is adapted
to cope with laptops which only have USB ports (which adapters work, which
don't, etc).

Many thanks,

Stewart
