Hi Artyom,

Thanks again for your interest.

The original serial ports come from a SCSI terminal server. A third 
party software from this terminal server maker (Central Data) is loaded 
at boot and create the devices /dev/ttyCx and load the proprietary 
driver in  kernel.
That's why those port are not in the devs tree. I can switch off this 
and replace the /dev/ttyCx with true serial ports. If it is possible to 
add a few ports on top on basic a & b native serial port, with custom 
device name, I think that could make it. But those new port has to be 
linked to host computer real ports to. This is far above my competence.
Though I used to (long ago...) be fluent in C and could get some support 
here, so I could volunteer to spend time on trying if I get just 
information of where to start and what to alter.

I did. Many thanks again.

Great step forward yesterday. I can now pass a serial port to the guest 
SS5, rename the device ttya to the expected name and then I can 
communicate with the software!!! This is really great!
So I come back to you about your proposal to add serials ports to the 
emulated ss5. This is just what I need now to go forward.
Could you please just give me the start point so hopefully I could give 
a try? Does only sun4m and escc.c need to be modified? Or is that much 
more complex?

Thank you for your answer. I am now so close to succeed !
(well, still need network, haven't had a look at that issue yet)

Kind regards,
Jean Michel
