 It has.

 Result is the same when mknod is issued on server.
 It is also interesting that both reading and writing /dev/tty works.
 Finally, I have tried mount /dev from SGI Indy ( OS IRIX 5.1.1 - also SVR4)
 and writing to /dev/null worked , so there may error on Solaris side
 ( no big surprise ).
