Hello,

Is it possible to have 2 navigation programs running under Windows 98SE
at the same time, using NMEA on the same serial port (com1)

Thank You
Philippe

All of them that I happen to be aware of are for NT/2000/XP. Search
on "virtual serial port" and you'll see some examples. Maybe there's
a 98SE version out there. Alternatively, you can add a serial port to
most machines cheaply. USB/Serial converter, PCMCIA card, whatever.
You could then drive both ports by tee'ing off the cable. What two
programs are you trying to run? There may be other options.

To reply, lose the capitals and do the obvious.

Take a look at cpRepeater, my NMEA data integrator, repeater, and
logger at http://www.worldwidewiley.com/

I was trying to run
Raytech 4.1 and MapSource (Garmin) at the same time

Tricky combination, depending on what you want to achive. If you only want
both programs to receive data from the GPS, the trick of adding an extra
serial port with a serial-usb converter will work. Be aware though, that
Raytech needs the GPS to be set to NMEA while MapSource probably wants the
GPS on Garmin protocol.

If you need to send data to the GPS too, it gets more complicated.
VirtualPlex-1 takes care of that, since it works with NMEA data only and it
can buffer up sentences from more applications and queue them nicely to be
sent to the real port. But with a separate real serial port, you would have
to decide which application may send data back to the GPS and hardwire that
particular port to the RX input of the GPS.

Yea, he's right...if you have 2 serial ports in your PC, great. If you have
a laptop with only one port, I'd go the route of the PCMCIA Serial Card. I
havent seen any USB adaptors that work 100%.

Serial Ports cant be shared, just so you know. So if you want the second
program to use what the first is using, it wont work.

How many do you want? I can supply you with adapters that even prevent the
crazy mouse problem in XP and win2K.

With a software utility you can. You can use Serial Splitter from
www.eltima.com or VirtualPlex-1 from www.shipmodul.com. The latter will also
allow all applications to talk back to the one serial port. The only problem
for the OP is that he runs Windows 98. Both utilities only run on NT4, 2000
or XP.
