COMTerm.exe

COMTerm is a menu-driven serial port test application (similar to HyperTerminal for the PC) for sending and receiving data over the serial ports at various speeds and with different flow control. Useful for testing a serial port quickly. Visual C++ source code included. This application was formerly called COMTEST.EXE.

Has COMTEST been tried on a CE.NET device?

I have used this on my Bitsy running 3.0. This morning I compiled another version of COMTEST under 4.0 and loaded it onto my BitsyPlus. The debug port does state that the COM1 serial port was opened, but the screen provides me with no drop-down menus.

Feature Update, Rev 6

We've modified COMTEST to be much more friendly and usable, adding the following:

Single pane UI for incoming and outgoing data.
Ability to capture data to a file.
Ability to send data byte-wise or in blocks.
Better menuing
Status Feedback

The new version of COMTest has projects and compiled binaries for eVC 3.0 and eVC 4.0. The binary compiled for CE 3.0 (COMTerm30.exe) is retargetable to CE 4.1. The binary compiled for CE 4.1 (COMTerm.exe) is not retargetable to CE 3.0.
