[comp.os.vms] DHU11 hanging problem in 4.6?

CAMPBELL@UTOROCI.BITNET (01/12/88)

Andrew Potter at Rochester (awpsys@ritvax.bitnet) reports,

> VMS 4.7 has been shipping since Jan 1st...it fixes a DHU-11 hanging
> terminal bug....

Terminals on my Emulex CS23 DHU emulator began hanging on ^C, ^Y and
^O if you hit them during output (which is usually when you want them
most) after I went to 4.6 from 4.4. They could be unlocked by killing
the process and (a) mucking around with set term/xon, or (b) waiting.
Is this the bug? I resurrected the 4.4 copy of yfdriver, and that
seems to have fixed it.

I figured this was an Emulex problem (bugs in VMS?!). Can someone tell
me one way or the other? The machine is an unclustered 11/780.

the DHV and DHU problems with terminal's hanging and such on input of
^C,^Y,^O was do to the modification in YFDRIVER of the YF$ABORT code for
4.6 and was a real mistake.  As of 4.7, the YFDRIVER has the 4.6 YF$ABORT code
replaced with the 4.4 code which works.
