I am going to need to use several serial ports at the same time for some video work I want to do. At least two of the ports should be RS-422. Is there a board out there that will let me add additional serial ports to the A2000? If so, how do I get commercial software to access the add on ports rather than the SER: device? If I can't get commercial software to access the add on ports, what good is an add on board? If I can't have RS-422 built in, can I buy an RS-232 expander and convert the signal to RS-422 compatible easily?
