Hey :D No need for credit, but the name's David Grierson if you feel like it .
I was reading a site about updating ipaq software roms (the OS, BIOS etc) and it mentioned connecting to the device via some sort of telnet-style software using the com port name for a serial connection, and also mentioned an equivelant port name for USB. It looked pretty much like a standard windows device location and I guessed since USB is essentially a serial bus in nature (it's in the acronym after all) it might just work with GPSOut - and it did! :lol:
Sorry about the port typo, was going from memory at the time :P
I 've yet to try this with other devices, but the Mio and the ipaq definitely work ok at the moment. With the baud set high enough (PocketFMS supports massively high baud rates, but I've yet to go past 19200) the interval can be set to sub 200ms levels, and the map display becomes pretty smooth. The main problem some software might have is that they dont allow changing of the GPS port on the PDA.
