Hello,
My OS is Windows 2000 Pro.
I am using the Motorola USB Modem driver labeled version 2.6.2 (part of the MSI filename), but when installed, in device manager, it's reported as version 1.6.0.0 with a file date of Dec 8, 06.
For Accessories Interface, Data Logging MCU Interface, Test Command Interface, and Motorola Flash Interface I am using drivers P2k.sys (v 2.3.0.0 dated July 28, 06), motswch.sys (v 1.0.0.0 dated June 8, 06), and motodrv.sys (v 2.2.0.0 dated July 28, 06).
P2KCommander does not connect with my phone properly (Version 4.9.

. It seems to know what com port the modem is on (13), but I just see it endlessly trying AT+mode=8 with no success. (there appear to be 2 unrecognized characters after the 8 every time. I presume they're carriage return line feed characters, but I don't know.)
Anyway, if I open Hyperterminal and set it to COM 13 and enter AT+mode=8, then P2KCommander recognizes the phone and everything works as it should.
Hope this helps you figure out what the problem is.
