We are currently considering this interface in a custom embedded controller design but based on your recommendations we probably need to reassess that decision. We were intending to use the parallel port through a super io chip on a custom designed board but it sounds like we should go with an ISA or PCI bus interface to get real-time performance at 1mbit baud rate.  Our application requires the full 1mbit baudrate continuous for 100msec to 200msec intervals.

FYI, I remember discussions about real-time problems with the PCAN dongle:

Can't remember where I got that information from, maybe from PEAK PCAN
support.

But that user did not have the problems you reported. Maybe it's
hardware related.

Wolfgang.
