iPort/AFM RS-232 Receive Buffer Overflow
Prompt: /I90[CR] ‘iPort/AFM RS-232 Receive Buffer Overflow
Cause: This event normally indicates that data sent to the iPort/AFM via the RS-232
serial port has been lost. Check the host computer’s RS-232 Serial Port Flow
Control (XON/XOFF, or Hardware) to make sure it matches current iPort/AFM
Flow Control. Also, check if the host computer’s FIFO buffers in its 16550 UART
are enabled. If so, reduce or disable Transmit Data Buffering. On Windows-based
host computers, see the Device Manager, COM port, Advanced Settings. You may
need to power down the host computer for any FIFO change to take effect.
