We extract TIOCGSERIAL section in f81232_ioctl() to f81232_get_serial_info() to make it clarifyYou're also changing 'ser.baud_rate' from 460800 to 115200. And explicitly overriding some previously initialized to 0 fields.
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 ;
The f81232_set_mctrl() replace set_control_lines() to do MCR control so we clean-up the set_control_lines() function.I don't see where are you doing this...
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.
