For Aztec C68 the following function will do the trick, the union and structure are as defined in the example "term.c". SendBreak() { long ticks; Control(PortA.refout, 12, &Csp); ticks = TickCount() + 14; /* use 210 for a Disconnect */ while (TickCount() <= ticks) ; Control(PortA.refout, 11, &Csp); } And it does work....
