Hi,

in -current (from start of this week) ps doesn't show the process'
tty.

E.g. (on alpha):

PID TT STAT    TIME COMMAND
199 ?? I    0:00.03 /usr/libexec/getty std.19200 ttyC1 
202 ?? Ss   0:00.31 /bin/bash -login 
207 ?? R+   0:00.02 ps ax 
198 ?? Is+  0:00.04 /usr/libexec/getty std.9600 ttyE0 
197 ?? Is+  0:00.04 /usr/libexec/getty std.9600 console 

There are only "??" there, same on i386.

regards,
chris
