About the cable...
According to PalmOne, Treo 650 used same multi-port as Tunsgten T5.
I downloaded PDF files from PalmOne and read about multi connector.
Multi connector has RX/TX Serial pins, but the output is 3.3V level. Not regular RS-232C revel.
There are several approaches to convert regular RS-232C to 3.3V TTL level. Using "Line Driver Chip". If you google "Dreamcast Serial cable", you can find many information. DreamCast Serial output uses same 3.3V level.
However, I choose more fast way.
1) Bought Tungsten T5 USB/HotSync/Charging cable at eaby around 10$.
2) Got FutureDial Mobile Phone Data Cable for LG 1200, VX6000 Model (Cable #19) at Radio Shack around 20$
3) Opened the dongle in the middle of FutureDial cable, and I checked the Chip. They used Prolific PL2303 USB to RS-232 Bridge, and line driver level is 3.3V WOW!
4) Disassembled the Tungsten T5 cable and FutureDial Connector, and Connected TX, RX, GND 3 pins.
5) Installed Future Dial USB2Serial Driver and run PST software.
Rock & Roll~
PS) I will post more details about the cable.
