Hi.
Data transmission on parallel ports is working, and they need to
interface the microcontroller with the PC now.
If you are sure that the data transmission is working from the Linux desktop
using that C code, it means that the Linux based computer is OK to be used
as a host or a slave to the micro controller's application. Beyond this, you
need to tell us what exactly you want for us to help you?! ?Is the micro
controller also running Linux?
Like what Thyagarajan said, normally micro controller apps are designed to
use the serial port unless of course you have a specific reason such as high
speed communication etc.
A word of caution through - Setup the parallel port in the BIOS setup as
standard SPP. Otherwise you will have to implement the corresponding
protocol in the micro controller hardware and software.
