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
