Packet Radio Networking with PalmOS?

Brian Hayward asks: "Does anyone have any experience using the Palm Pilot with packet radio? I'm interested in using my Palm IIIx to connect to my home Linux computer in a wireless fashion, but I don't want to pay the ridiculous per minute/per kbyte charges that are currently levied on wireless data users in my area. I know it's possible, but I'm not sure that the PalmOS software exists to do this. (I haven't seen AX.25 software for PalmOS yet). I know the software exists to do this on the Linux side."
