Hi Waldek,
Thanks once again for your response to my question about keying through the
LPT port on my computer.
>>1) HF interference (I'm sure, you tried this, but...)<<
As indicated previously, I eliminated this possibility by keying only the
sidetone.
>> 2) If W1WEF interface is working properly with CT <= 9.27 and
shows above behaviour with later versions you need to modify the
keyer. <<
Also, as indicated in my previous response, I do not believe the problem is
software-related. I can key the IC-765 through com-2; I'm key down until the
"first beep" using com-2, just as you describe it. Everything works fine
after that first key down.
>> Look in the manual of CT, you'll see that there are 2 lines for keying:
enable and key. I dunno remember pin numbers (I don't have my manual here, I
think it were 1 and 17). <<
I investigated this possibility, but as far as I can tell, the pins are
correct.
There are two possibilities that come to mind at this point, but both are
WAGS. First, the Maxar 486/20 system I'm using with CT 9.48 is not
compatible with LPT1 keying to the IC-765, but this seems unlikely since the
port has run printers fine for nearly 10 years. (The machine originally had
a 386 processor.) Another possibility is that I need a TSR for the LPT port,
but the manual doesn't mention this.
Can you or anyone else on the list come up with something?
