Changing the trigger level of the Serial.
I'm working on pcPentium.
I have a serial which is 16550 compatibale.
I'm using the i8250sio driver.
After the driver has been init I enable the fifo and change the triger level to 4.
This is done by writing to the IIR:
sysOutByte 0x3f8+2,0x41.
I do get inturrpt but sill it is for every byte coming while I want to have interrpt every 4 byte coming
