Hello Farhad,
1. The PC/104 is compatible with our AT-GPIB card for PCs and comes with the NI-488 DDK so that you can write drivers for platforms that we do not support. We have a DOS driver that should work for you at: http://www.ni.com/download then click on "Drivers and Updates" >> "Current Software Versions" >> "GPIB Plug-In Controllers" >> "Various Versions DOS" >> "AT-GPIB/TNT version 2.7.2".
2. LabWindows for DOS should allow you to quickly and easily write an application to interface with your GPIB board and perform any necessary computations. However, DOS does not have the MS "winsock" and LabWindows for DOS does not have a built-in TCP library. You should research with your Network Interface Provider to see how to interface with their board under DOS. A
lso, LabWindows for DOS (latest version was 2.31) is no longer for sale from National Instruments, so you may want to post again with your interest in purchasing a used copy of LabWindows for DOS. There is also the unofficial listserv at http://www.welcome.to/cvi which you could post to see if anyone there has an old copy for sale.
3. This should be easy enough with LabWindows/CVI(for Windows).
