Hi Folks,
On Thursday I foolishly wrote:

There seems to be a problem with keystrokes not being delivered to a
process with a read pending on /dev/tty, under DU 4.0b.
There are two circumstances in which we have seen this.
1) The operators start an xterm on their workstation, and rsh to a machine
with a tape drive, then by means of sudo proceed to run a script called
backup with root privs.

Thanks to Tom Blinn, and everyone else who replied.
The problem was a bug in the script. Two processes, the `dd'
process and the `rsh' process both had reads outstanding on the keyboard,
and all the missing carriage returns had been delivered to the `rsh'
process.
The script is now modified to say
...
rsh <remotehost> dump 0f - <fs> < /dev/null | dd of=<tape>
...
And it seems to be working.
I feel very foolish...
Keith
