(My 300MHz P-II only has LPT1)
When you mention DX4WIN, I infer that you were running Windows 95?, on your old
486. To run PURE DOS as Brian mentioned, you must reboot and select DOS Only -
that leaves you with a command prompt only. Is that what you're doing?
Or are you running CT in a DOS window???
I made the same mistake getting a keying line on COM3. I used LogEQF, a very
well behaved DOS program, which I almost always use in a DOS window. When I
finally put a volt meter on the DTR line there was no activity. I then tried a
windows program, TRX-Manager, and it works fine.
1 Boot directly to DOS
2 Eliminate the rig question by putting a voltmeter on the keying line from
LPT1.
3 I recall that CT will also work with DTR on a COM port. And you may be able
to use DTR for CT even if the data lines of the COM port are used for something
else. (Plan B - hi hi)
Good fishing,
