Run 2 GPS ???

Ok, I had an idea and need you guys to shoot it down.

Seeing how we cant port share PPC yet allowing us to simultaneously log AP's and run mapping software at the sametime restricting us to one or the other.

Would it be possible to run 2 different GPS's on different ports?
Say a Sapphire on COM1 and a CF GPS on COM2 and then run MS and mapping at the same time just by configuring the given software to recieve GPS from different ports.

yes, just configure the appropriate ports in each client

So, for the FAQ

Can you run MS and mapping software at the same time?

Why, yes. Yes you can. You just need 2 GPS units configured on different ports.

Wouls you be able to use One gps device for two applications tho?

As far as I know, No. Not with PPC. Thats why I posted using 2 GPS's. You can do it on a laptop though.

One GPS + splitter cable + two serial ports = Ministumbler & moving map at same time.

The limitation about running NS (or PW) and mapping software concurrently is that both want full control of a serial port on which they will listen for NMEA sentances.

The issue for most of us is that we only have one serial prt, the sync port. Add a second serial port and the two applications can have one each.
One place to get a single card with two serial ports is, this would go well in a dual PCCard jacket on an iPAQ alongside your favourite NS compatible WLan card.

Now we ask ourselves, how do I get one GPS to supply data to two serial ports?
The great news is that since we are only listening for data from the GPS (not sending any data to it) this is quite simple. Connect the ground pins of the two serial PPC ports to the ground pin of the GPS serial port. Then connect the data out pin of the GPS serial port to the data in pins of the two PPC serial ports.

Personally I'm still hoping that Marius will offer us a GPS API for NS 0.4 that will allow my little eVB application to send it NMEA sentances the way that it sends them to OziExplorerCE ( or for the main site)
