Hi Experts,

I would like to know  if you can point me  to a tutorial/sample codes  on  how  will I be  able to create an application with  similar  functionality  as  wireshark+winpopcap  but instead  of capturing  all network communication, it  will capture  data  passed  through  GPIB  and parallel  interface.

If possible  I would require  sample  for  Unix  and windows  OS ..

    Parallel its the easy one with harware+api a standard everywhere..

    GPIB it's a different thing, no standard hardware/drivers/api on the PC world... then you need a propietary solution probably following IEEE 488.1 / 488.2

    NI has a well know interface  NI-488.2 with drivers and api, from there to a data logger just one step.
    you have also GPIB-ENET/¿1000  a gateway from the GPIB world to ethernet then you could go from there to wireshark and probaably just coding a wireshark protocol module you get all the wireshark framework...
