Vb6 Serial Port Sniffer Source Code

If you have control over the first program that talks to you COMM port, why not change the program to pass data received from the port to the 2nd program of yours via remoting or any other type of IPC. Better still if you can write a proxy program that connected to the COMM port, and have 2 of the other program talk to this proxy to get the communication done. Another idea is, if you need to sniff only incoming data, you can get a Y-cable (splitter) and connect to 2 COMM port, each program connects to each COMM port. But you need to make sure the 2nd program is not trying to transmit. In some cases you might need a splitter which only connects the RX pin for the 2nd output. Let me know if you need the diagram.

If you don't have 2 COMM, you can easily get a USB-Serial Converter for less than USD10.

CAN232 do not require a special COM port driver, since COM ports can be read and written to without any. Sample code in source code which we made or others have provided to us. C# CAN232 Monitor Lite (Version 1.0.0, 32bit Windows Installer). To be able to compile and change the code you need the VB6.
