My programe run at lower version compiler say 7.3.3P but when I recompile in 10.72D. The confuncs run in costate have hit a “System Mode Violation” and stop… The cofunc run healthy individually but when put two together problem occurs. The cofunc will run RS232 in PORT C talked to terminal and control some simple IO output in PORT A & B. I try Tcpip routine if IO or serial port functions are involved. Problem will occur.
Any solution?
