[net.decus] Turning off the VMS LOGINOUT process at a terminal

levy@ttrdc.UUCP (Daniel R. Levy) (08/30/85)

Dear Net.Decus:

Is there a way I can squelch the continual respawning of LOGINOUT at a VMS
terminal line which would otherwise be excited by characters coming at it
when it is not allocated or otherwise in use?  I have a terminal line which
I want to connect to Datakit as an outgoing port, to be used only as initiated
from inside the VAX, not from the Datakit line.  But I want then to use it for
two-way communication (not like a spooled printer or the like).  I have tried
things like $ set terminal /nointeractive device:  which does not seem to
work.  The problem with having LOGINOUT at the terminal is that it keeps having
a constant conversation with Datakit, with a lot of Username:  Password:
User authorization failure while Datakit is going Username: IS AN INVALID
DESTINATION  Password: IS AN INVALID DESTINATION  User authorization failure
IS AN INVALID DESTINATION with the result that VMS and Datakit are driving each
other wild.  This leads to difficulties when the terminal is to be allocated,
from a batch job.  (I solve it by sitting in a loop trying to allocate the
sucker until I catch it at just the right time or have tried a couple of
hundred times with no luck).

Any clues or help would be mucho appreciated.  Thanks much.

Yes, this is easy.  SET TERM TXA1:/NOTYPEAHEAD/PERMANENT will do the trick.
On VMS V4 you can set it /SYSPASSWORD and it will not only solve the login
war but will still let you log in if you type the system password first.

The trick is to $ SET TERM/PERM/NOTYPEAHEAD...

This was discussed recently in fa.info-vax. The only known to work answer
is Set TERM /perm/NOtypeahead. Basically this keeps the driver's buffer
empty so the loginout's ast is never triggered. Allocate the line and
reset the characteristic when you want to use the line.

Thanks to everyone who wrote or posted suggesting a solution to this one.  The
answer I arrived at (which oddly enough nobody mentioned) was to

$ SET TERMINAL /NOMODEM /PERMANENT  DEVICE:

and reverse that after allocating the device in the batch job.  I have not yet
tried the other techniques, which may work just as well.  Thank you all just
the same.
