WCE 2.0 and Mitsubishi MobileAccess 100

As of this writing (mid 1998), Mitsubishi has not published the "AT Command Set" for Mitsubishi MobileAccess 100. Further, at this time connecting WindowsCE devices to the MobileAccess 100 is not supported by Mitsubishi. However, we have managed to use MobileAccess 100 with WindowsCE devices.
Below is the summary of key pieces of information that you need to know.

Getting The Mitsubishi MobileAccess 100 Cable
You need a special cable that let's you use the Mitsubishi MobileAccess 100 phone as a CDPD modem. The required cable is part of what Mitsubishi calls the "PC Connection Kit". Its price is very unreasonably (about 100.00 US Dollars, as of mid 1998).
The Mitsubishi MobileAccess 100 Cable is terminated with a female DB-9 configured as a DCE (Data Communications Equipment).

Connecting the Cable to WindowsCE
Getting the cables to work is the trickiest piece.
WindowsCE cables are terminated with a female DB-9 configured as a DCE (Data Communications Equipment).
In order to connect the Mitsubishi MobileAccess 100 cable to a WindowsCE cable you need a male-male DB-9 null modem cable.
We can build some custom WindowsCE to Mitsubishi MobileAccess 100 cables. Contact Neda Communications, Inc. for more information.
