Ok. I try now with 9600. There is a 16550 on the board.
So... should go up to 115200? But for now, it's ok
to test with 9600 to be sure.

Yeah! good. Now, I am be able to set baud etc. With the adress.
I used: (for ttyS1) 0xf0202800
I don't have error now when I try to change baud_base. But...
If now I try to do pppd & (with parmeters in /etc/ppp/options)
I have this:
sent [LCP ConfReq id=0x1 <asynmap 0x0> <magi 0x4e302ccd> <pcomp>
read: Ressource temporarily unavailable
read /dev/ppp: Ressource temporarily unavaible
(these messages 10 times)
+ Exit 10 pppd

Of course! What's I want to do! I want to enable PPP over
the serial to my other PC Debian to be able to fetch the new
kernel and all updates... ;o)
Also, I am not familiar with this kind of industrial computer.
There is a DB9 connector for network at rear of the machine.
What do I need to connect it to my HUB (RJ45 Ethernet).?
And finally, to have an idea, 715/100 PA-RISC is equivalent
of wich Intel Pentium speed? I know it's not the same at all
and there is a lot a variables to measure computer performances
but anyway, just to have an idea ?
Thanks a lot!
