WARNING messages of se driver

When a serial port receives a lot of data, such as when a large amount of text is pasted on a console screen connected to a serial port, the console message "seN: Buffer overrun" (N means an instance number of se driver) will be displayed and the data will be lost.

This is because the user process cannot read data fast enough.

The size of data pasted on a console screen should be 1024 bytes or less at a time. Speed of reception depends on each user process.
