Hi,

My application occasionally had this C0000005 error and the screen
will show the calling program line and below is the line that
indicate causing the problem. The STX,ETX and DLE are constant
define in the header file. It will output some character to the
COM port. Anyone had any ideal how to solve this problem.

Thank you very much

lBuf = INT(VAL(lChar))
IF lBuf = STX OR lBuf = ETX OR lBuf = DLE
THIS.OutPort(CHR(DLE))
lLRC = BITXOR(DLE,lLRC)

ENDIF
