X.25 on SunFire 240 !

I am trying to configure X.25 software on Sun Fire 240 Server. What is have
concluded is that /dev/zsh device is required for the X.25 software to be
able to work. This device is not available on solaris 8 on SF 240. I have
X.25 running on old ultra 1 where /dev/zsh exists. What is figured out is
that /dev/zsh is for serial synchronous port however the Serial port on SF
240 is asynchronous. I believe that old sun system's serial port support
both synchronous /asynchronous modes.

Any suggestions !

I will summarize

thanks
