setserial /dev/ttyS5 uart 16550A port 0xdfe0 irq 

11 ^fourport

Since the PCI-485 supports a higher 

baud_base

 of 460.8K at start-up, also 

enter the following at the linux prompt:

setserial /dev/ttyS<

port number> baud_base 

460800

For example, enter the following to assign the serial driver to 

/dev/ttyS4

 

for a PCI-485 serial port at port address 0xdfe0 and IRQ 11.

setserial /dev/ttyS4 uart 16550A port 0xdfe0 irq 

11 ^fourport

setserial /dev/ttyS4 baud_base 460800

Enter the following to assign the serial driver to your devices for the PCI 
eight-port 

lspci

 output. Notice that the entries for port are consecutive 

and are separated by exactly 8 bytes.

To enable the PCI interrupt on your serial interface, use 

intenable

, 

provided in the 

PCI-SERIAL

 directory. Run 

intenable

 each time you 

restart your computer. If you have more than one PCI serial interface, rerun 

intenable

 with another PCI memory address specified in the command 

line. Enter the following to use 

intenable
