Description

The Null-modem emulator (com0com) is a kernel-mode virtual serial port driver for Windows. You can create an unlimited number of virtual COM port pairs and use any pair to connect one COM port based application to another. The HUB for communications (hub4com) allows to receive data and signals from one COM or TCP port, modify and send it to a number of other COM or TCP ports and vice versa.

    If you have trouble with Windows signed drivers, use version 2.2.2.0

    Just like Martin I can't use it because the driver isn't signed. Great shame I've heard nothing but good about it.

    Very good tool! I've used it with com2tcp to redirect com from another pc. Works like a charm

    I found bug :) There is problem when I'm opening one of these virtual port with my app (.NET, VS2008). While second port is open is ok, but when it is closed, main app is 'frozen'. It's 'defrost' in the same time when i opened second port (no data revivied). System is Win7 pro x64
