I have a Garmin GPS that I'm trying to connect to my Compaq V2310US
laptop, running XP Pro. I have purchased two different usb to serial
adapters and can't seem to make either play. Garmin's software can't
find the GPS with either. When I hooked up the first one, it gave me a
com7 connection, however garmin doesn't look at anything other than 1-4
so I moved it to com2. No play. I connected a breakout box to the
serial end and jumpered 2 and 3. I went into hyperterminal and
configured to talk with com2 and I can't see what I'm typing. I then
connected 4-5 and 6-20 in case it wanted some handshaking. No help.
The port is hot, since I see lights where they should be.

I get pretty much the same results with the other cable.

I brought Linux and minicom on a different system and the cable/breakout
box seems to work OK

Any ideas?

Thanks,
Jim.

Note, it's not the laptop hardware, minicom on Suse 9.3 finds the port
and communicates just fine.

I did, they said, "buy a cable from us".

This is good news. It means two things: your GPS does support a
USB-serial cable, and one is available that works. If they want less
than $30 for it, I'd just buy it and be done with it. And if it doesn't
work, get a refund. Of course, if one of the cables you bought, that
don't work is from them, return it.
