rn under 3.51

[M. Anthony Kapolka 3]

In my continued quest to get my system working under 3.51, I've noticed
users on /dev/ph1 can't open /dev/tty.  This is most obvious under rn...
which doesn't work properly.

I'm told that this is due to a bug in the ph1 driver.

Can someone give me some more info about this?   I'm not eager to modify
rn, since the same executable worked under 3.0  (and it should work now!)

Thanks in advance!
