I have tried the default baud rate of 9600 the program uses 9600, 1200, 2400, 4800. I have tried all these rates but no luck. This is a program that speaks to another on a windows PC. This happens whether or not the cables are connected to the ports. Question is what are the supported baud rates or could it be windows7.
Each time the program is launched in 2 seconds the error pops up and even when you choose to ignore no communication happens.
