I have made one applcation in which I need to send and read data from two different COM port one after other in random manner during testing.
My development PC has WIN7 in which it is working fine. but other PC in which I am installing my application has XP SP3(Successful installation) in which when after sending to one com port in other when reading from different com port I am getting timeout error.. It was working before but now it is failing mostly.
Sequence is like this.
1. COM1- read + write - success
2. COM1- read + write - success
3. COM1- read + write - success
4. COM2- read + write - failed
I dont know what could be the reason. Previoiusly it was working fine but now its failing. Everything is same with no change.
Any suggestion is great
