Ed, et al,
This doesn't surprise me at all, and it shouldn't surprise anyone who tries
to run DOS apps under Windows. Way back at WRTC 1996, we discovered that
the brand new (for then) TI 5200 laptop running brand new (for then) Win 95
would key fine from a COM port, but not from an LPT port. The exact same
version of NA worked PERFECTLY on a Win 3.1 laptop.
The fact that the radio control interface provides a clue that its not a
BIOS issue, and NA is finding the base address of the COM port
correctly. Since keying uses the "handshake" or "control" lines, I suspect
that Windows is insinuating itself between NA and the port. I have no clue
how to get around this.
This past weekend I bought a pair of used Acer P233MMX desktops for $70
each at a computer show. Their intended use is for a new 28 MHz position
at the K8CC multi-multi. These computers were surplused out of a local
school system. They boot up to a command line prompt (looks like DOS), but
when you do the VER command it says "Windows 98". (There is no Win98 files
on the machine - our best guess is that the HDDs were wiped clean, then
formatted with a bootable floppy from a Win98 machine.) So far, in testing
these run NA just fine - for LPT keying and rig control.
This probably provides no useful data for Ed's problem, since LPT keying
and rig control work's in his case as well. If I can find a COM keying
adapter (not too common around K8CC) I'll test it for COM keying as well.
