RS232 in Windows XP with PIC programmer

I would like to reprogram a EEPROM, however it seems that my Serial Port does not provide power when I enter Windows XP. Under Linux, the JDM PIC programmer's LED lights up, however I need to use Ponyprog in Windows.

 

I see there is power to the programmer just until I enter Windows.

 

Any ideas?

 

Thanks

Hello mate,

 

Try to see in the device manager if windows does not turn off the port to save energy.

It's the only option I see for the moment. I try to look further if it's not the problem.

Re: RS232 in Windows XP with PIC programmer

Hello,

 

Thanks for the suggestions. I tried using the COMdisable tool from Microsoft, but it has not changed the status of the status of the port. It is still visible in the Device Manager as serial port COM3.

 

Needless to say, the BIOS does have the serial port enabled.

 

Unfortunately I have the same results using this Thinkpad A31 on a dock!

 

Cheers

Re: RS232 in Windows XP with PIC programmer

Apparently it's a problem of I/O port. Windows XP have a strict control over I/O port.

 

Have a look there : http://www.beyondlogic.org/porttalk/porttalk.htm

 

Hope it will help
