How to change port? - by: astromout

Hi,

I now work with Kstar-Ekos. On my new computer I have a RS232 port on it.
I'm on ubuntu.
With "setserial -g /dev/tty[0123456789], it gives : "/dev/ttyS0, UARTY 16550A, Port : 0x03f8, IRQ : 4"
So I tried : sudo indiserver -p 0x03f8 indi_lx200basic

It returns : Driver indi_lx200basic: Initializing from LX200 Basic device...
And, nothing appen, I have to do ctrl-C.

Could anybody help me?
Thank you.
Astromout.

kstars 2.9.7
ubuntu : xenial (I don't want yet to upgrade...because every is working )
