Hai

I have a MicroPro DIY programmer and is working fine so far.



I have a PCI add on card in my PC to emulate two serial ports.


Automatically on driver installation they have automatically assigned as COM3 And COM4.


My DIY programmer works with COM1 very well.

But on COM3 and COM4 it is not properly working.

The programmer is detecting by the software on that port,but cant proceed.

From the messages it seems that signal comes into the PC from hardware.But Software cannot send signal or data out.

Any loopholes with such serial ports?

Solutions please
