F81232 max baudrate is only 115200bps, so I set it for
1.8432MHz/16 = 115200.

We had add some closing time referenced from serial_core.c. The default
value is:

port->close_delay     = HZ / 2;	/* .5 seconds */
port->closing_wait    = 30 * HZ;/* 30 seconds */

We had increasing close_delay about 10x to

port->close_delay     = 5 * HZ ;

This text is my patch V5 5/8 second section. I had wrong operation of 
copy & paste. It's doesn't need for this patch, sorry for it.
