hi gayan,
I have just posted a RS232 serial debug program on
www.manorts.com/phpBB
its named amcomm1.zip. Download and unzip, give it a test drive and see it
meets your requirement. [ you will require the free VB runtime files from microsoft].
I would welcome any comments you may have on the program.
If you have Visual Basic 5 in your PC, I could send you the source code, so
that you modify the code to suit your project. Send me a PM if yes.
Its written as a RS232 debug utility tool, with lots of features.
Regards
EricG
