Are there any motherboards out there that have many serial ports directly on them? I have been using large 8 and 16 port serial to USB boxes, but there is a small amount of latency associated with these. Timing is very critical with my work and I would like to eliminate as much latency as possible. I have worked with newer motherboards that have one or two serial ports on them, but I am wondering if you know of any that have more than two. If there are not any with more than two, do you have suggestions on a good motherboard with two? Having the ability to add plenty of memory and and good video cards are also important. Any help is appreciated.
