Hi Dave, thanks for your comments. I think you are correct in your appraisal of the situation.
I am using a Windows 2000 Professional workstation (Beta 3). We have some java and non-java apps that need to access the card reader/terminal. We bought the GCR410P specifically because it was supported by W2K (plug and play) and did not require any additional drivers to be installed (I assume the PCSC drivers are already installed into W2K). I tried disabling the device from the control panel. The COM port becomes available (i.e javax.comm does not complain) but then I can not get any response from the GCR410P.
Any idea on how to disable the baked-in (Plug and Play) drivers and keeping the GCR410P functional? Are Plug and Play devices physically disabled (some enabling/disabling flag) when they are disabled from the Windows Control Panel? Is it possible to override this behaviour somehow?
Thanks
Pieter Kasselman

When you upgraded, did you install PCSC drivers ?
The most common cause of this error is PCSC drivers grabbing the serial
port which prevents java.comm from using it and results in this apparent
inability to communicate with the card reader.
I have certainly seen it with the Litronic PCSC driver, and recommend
that you investigate this area.
Regards
Dave
