You need to set up the Dev.ser properly.
How did you start it?
Tony.
Also, make sure they are all enabled in your BIOS setup.

In bios have:
COM1=03F8 COM2=02F8 COM3=03E8 COM4=02E8
and COM PORT: Enable
but in my computer COM1 have form COM port 9 pin and COM2, COm3, COM4 have
pin header form.

Once again: You need to set up the Dev.ser properly.

I use
Dev.ser 2f8,3 -N /dev/ser2 &
and in /dev i have /dev/ser1 (COM1) and /dev/ser2 (COM2)
then
Dev.ser 2E8,3 -N /dev/ser3 &
i have ser3
Why ? because IRQ is 3.

Try starting it this way:
Dev.ser -t8 -b115200 &
This will make it to search for all the serial ports available.
If you know the actual port addresses and their IRQs, then you could start
the driver this way:
Dev.ser -t8 io_port_1,irq_1 io_port_2,irq_2 io_port_3,irq_3
io_port_4,irq_4 &
Where: io_port_N is the according COM’s address and irq_N is it’s
interrupt vector.
Do not force names with -N, why do you do it?
