We recently installed HP-UX 6.5 here.  Two items appeared almost
immediately:

_P_r_o_b_l_e_m_ _1_:

We have some ksh scripts (beginning explicitly with '#!/bin/ksh') that
take advantage of the job syntax '%jobno'.  The scripts launch a couple
of jobs in the background, perform the foreground task, and then do a
'kill %1 %2 ...'  to terminate the background jobs.

With HP-UX 6.5, the message "kill: %1:No such job" is issued if this is
attempted from a script.  This still works fine interactively.  Try:

	sleep 5 &
	kill %1

both interactively and from an explicit #!/bin/ksh script to see what I
mean.  I've read the 6.5 update notes, and thought that this might be a
side effect of the new job control, but I can't seem to pinpoint it.

_P_r_o_b_l_e_m_ _2_:

We access our 370 here mainly over a Sytek LAN.  These Sytek boxes are
configured to disconnect the current session when it sees DTR drop.  DTR
is supposed to be dropped by the system when a user logs out, until the
next getty opens the port.  This is no longer happening with HP-UX 6.5.
I see no reference in the update notes about the tty drivers changing.

Many thanks in advance for any pointers regarding either or both of
these problems.
