faq	card test

The message was:
We need to implement a reliable method to test if the installed PCL-PCI card is properly. Can you provide us with information about the PCLtest program and supply the source code?

The source code is included in our SDK we ship on a disk with the PCL-PCI. It's located in the sub-directory \sdk\pcltest. You may download the last version from our website.

If you want to implement your own diagnostic code, you should call pclOpen() and check the return code. If it is less than 0, you may convert it to a string, as shown in err2msg() in PclTest.cpp. Additionally you should call pclGetErrorString() to get a more detailed error message. Both information, the pclOpen() return code and the result of pclGetErrorString() are helpful to find the problem, if the PCL-PCI doesn't work as expected.
