Serial Watcher is a small piece of program from PCRemote Control that can watch the data flow through any of your serial ports live and save the flowing data. It’s main use is during the testing of serial data receiver devices. I found this program while I was making a remote control for my PC.

Serial Watcher is an installation free, light at 150Kb zip package and can open/ monitor up-to 9 serial ports. The serial port watcher sadly cannot work as a sniffer which can show you all the data flowing through a serial port. It is not capable of opening ports that are already in use.

Features :

Parity bit, data width, no of stop bits, Hardware and Software handshakes all are changeable to all possible values, works with Windows 95/98/ME/NT4/2000/XP, saves data as text files, timestamp option available, data can be viewed in HexaDecial, Decimal or Binary

Pros :

Easy to use, highly customisable and adaptive to incoming data protocol, istallation not required,light and free

Cons :

only available for Windows, can’t act as a Sniffer

Specifications :

Memory usage : 3.1Mb
Virtual Memory : 28.3Mb
