ASSIGN serial port to virtual device

Bodo Wenzel

There is a nice virtual null modem cable (http://com0com.sf.net) which saves me from installing hardware on my pc to get 2 serial ports. It works well with most applications, 3rd party and self written.

To (automatically) test my ARM program, I'd like to ASSIGN one of com0com's ports as the serial device of the simulated ARM. (BTW, this is the internal UART0 of a LPC2292.) But the simulator can't use it, only COM1 to COM8.

Any suggestions what to do are welcome! It might be a hint to trick uV3 (versions: uVision3 V3.12a, CPU DLL SARM.DLL V1.27e, Dialog DLL DARMP.DLL V1.09) into using the virtual port, another (free) virtual null modem, an AGSI DLL which connects to a virtual port, a simulator script ...

    This would be a really useful feature for Keil to build-in to uVision!

    Very often embedded microcontroller projects need to communicate with a PC or other devices over an RS232 link.
    The uVision Simulator is ideal for testing/debugging the RS232 comms, but having to use two physical COM ports (or two PCs) and a null-modem cable is cumbersome.
    A virtual COM port would be great!
