CT9.27 Pinout.

[George Cutsogeorge]

I've been doing some probing with my scope and don't think
the pinouts shown for LPT1 at the CT web site are correct.
Pin 16 responds to the "alt ." command, so it must be the
Radio1/Radio2 signal and not PTT.  It's high for Radio 2 and
low for Radio 1.  The CW keying and Band info are the same as 
previous versions.

Don't have LPT2 here, so no info on that.

Could someone with 2 LPTs verify what pin 16 is doing on
LPT2 when it's setup for Radio 2?
