Query: DO NOT BUY - DOES NOT WORK!

After spending many hours (phone and email) with tech support I was able to get this device to function with 2 of them back to back with each other and transfer files via x-modem PC to PC (as a test). I did not buy them for this purpose (Wireless or wired LAN is MUCH faster!).I was able to limp along to provision a box at 4800 bps (software port speed setting only) via bluetooth adapter to one of these using HyperTerminal (not available on my Vista PC, had to download TeraTerm freeware replacement). I had to wire an adapter to loop pin 7 to 8 toward the dB9 of this adapter because it is not capable of turning off the hardware handshaking. It still would not work with products I bought it for and on XP and Vista PC's both I get the Blue screen of Death every time I point the software at the GSB301 COM port!
