We are trying to debug the data stream coming from a medical monitor to pc-based software through a serial port (com1)
We need to record the data stream (it is a binary data stream, not ASCII), look at it, and be able to play it back (out com2, through a null modem, back into com1) to mimic the original data stream.
Have downloaded HHD Software- Serial Monitor Ultimate and also Eltima Serial Port Monitor. HHD Software looks more powerful, but can't get either to play the data stream back out com2. Tried copy /b log.bin com2
but device driver on com1 didn't see anything connected ("CTS low on COM1)
Any suggestions, or better software for accomplishing this?
