I am looking for any info on how to program (& wire) the
Cassiopeia E-100/105 (and probably 115/125) WinCE 2.11 PDA,
to communicate (I mainly need to send data) with a microcontroller
(ie BASIC STAMP, PICAXE) using its serial port.

For software I am programming in eMbedded VB 3
(I also have C++ installed on my system though I am less familiar with
it).

I have not found any info on pinouts for the e-100's serial port
but a couple of posts online said to connect the PDA's serial DB9
cable
(I assume they mean the one with the cradle) with a null modem
adapter.

Does anyone have any related info/links/etc?

In C/C++, you use the standard file handling functions (CreateFile,
etc.). I assume VB is similar. The ports are called COM1:, COM2:, etc.
(note the trailing semicolons for CE, unlike "big" Windows). For more
info, look for a tty sample in the SDK files.

I _think_ the e-100 has a CF Slot. And I'm pretty sure Socket
(www.socketcom.com) used to make a CF -> serial adapter. May be worth
checking.

Almost all Windows CE devices with serial ports are set up as
non-computer (because the primary reason for the port is to connect to
a computer). So when you want to connect to another non-computer you
need to use a NULL modem.

I used serial to connect some other Windows CE devices (HPCs and HPC
Pros) to instruments. Standard serial cables plus a NULL modem worked
well.
