[RTTY] Trouble with MMTTY/EXTFSK

[Edwin Karl]

FOLKS-

When I first turn the computer on, I go through one or 2 PTT events 
followed by a continuous
PTT presence. I am using LPT1 pin 2 for FSK and pin 6 for PTT pin 20 for 
ground having
found pin 25 is not grounded in the computer. All per K0RC info (which 
is very well done,
I learned a lot from it).

When I then open MMTTY and EXTFSK the PTT usually goes away. ANy way to 
eliminate
it, I'm sure it's in the software. Unplugging the cable clears the PTT, 
reinserting the cable
brings back PTT.

Any ideas?
