I wonder how this Software works ?
I wanted to make something similar and had the idea to create a virtual com-port, which would tunnel applications to a 'normal' com-port.
But the above software is much better. It seems it reads the send/receive - buffer of the serial device somehow...

Does anyone have an idea how this is possible ?

impossible to do a virtual driver unless you know good ASM and knows
how to do windows VXD files or somthing like that.

this is what i found regerding virtual comport
