Hi folks,
I had problems with recently downloaded v9.39, so I switched to
v9.27 during last ARRL contest. Description of problem:
I use my 'home-made' keying interface (optocoupled) attached to
LPT1 many years. First with PD software, after purchasing of
commercial version, with v8 and 9 (9.27 is my last used version
prev. to 9.39). It worked fine. But: v9.39 is very strange. The very
fist beep (tune, or cq-ing or anything else keying the rig) causes lpt
port to 'hang' (i.e. tune-beep). The same after terminating CT. The
only way to switch it off is restart computer, or :-)) start version
9.27 of CT and start keying. It is not a HF problem, because it
'works' also without rig :-))
Any ideas??
Computer: 486-66 with 40MB memory, LPT1 address 0x3BC and
Windows 98 in dos mode. No other connection (rig control or
packed) attached.
