Communication-buffer overflow
During remote communications, the receive buffer
overflowed.
 
The size of the receive buffer is set by the RB option
in the OPEN COM statement. To avoid this error, you can:
  ■ Check the buffer more frequently using the LOC
    function.
  ■ Empty the buffer more often using the INPUT$ function.
 
ERR code: 69
