PS1832 Overrun Error (2)
The next character was received from the I/O device connected to reader/punch interface 1 before it could read a previously received character. An overrun, parity error, or framing error occurred during the reading by reader/punch interface 2. The number of bits in the entered data, the baud rate setting, or the I/O unit specification number is incorrect.
Quick tip:
Check RS232 parameters 20, 121, 122, 123 and I/O setting
