I wish to read and write to the serial port and its associated registers.
I can read and write to the parallel port using /dev/port and address
hex 378. I can also read the command and status registers by using port
378 + 1 and 378 + 2
The serial port base address is hex 3f8 ( ttyS0 ) plus the various
command status registers, 6 in total.
My question is can the serial port be controlled in the same manner,
i.e. using /dev/port where the address is either 3f8 plus 3f8 +1, 3f8 +2
In other words is /dev/port a general purpose I/O port ?
