Subject : communication error on debugger: "overrun"
Keywords: Communication - error - debugger - overrun
Concerning communication between ISaGRAF debugger and target:
The error message "OVERRUN" indicates a synchronization error while
receiving characters (on debugger side). This generally corresponds
to a character received on the RS line before the preceding one is
read by the debugger. This can appear under Windows 3.1 if the
system is blocked (ex: some mouse manipulations).
This is a non severe error, due to the system behavior, and not due
to the safety of the communication link.
Intermediate states "disconnected" or "appli XXX active" are the
normal re-connection procedure run by the ISaGRAF debugger after any
