[comp.sys.dec] dxterm not working right for VMS

mcguffey@muvms3.bitnet (Michael McGuffey) (09/19/89)

I'm having some problems getting dxterm on a DECstation 3100 to work
when DECnetted to a VMS machine.  We do a SET TERM/INQUIRE in the system 
login and a SHOW TERM is identical with a SHOW TERM from a SET HOST session
from VAXStation 2000 running VWS.  A few things that seem odd follow:

	1. Control-Z, Control-C, and Control-Y all echo from the VMS
		machine as ^Z,^C,and ^Y rather than the reverse video
		Exit,Cancel, and Interrupt.

	2. The arrow keys do not work properly for command line editing.
		I've tried both application cursor keys and normal cursor
		keys in the GENERAL setup for dxterm and neither setting
		works properly.

All of this is while using VT300 mode,7-bit controls.  SET TERM/INQUIRE
returns an "unknown terminal type" when using 8-bit controls.

Anyone have any suggestions?

I'm assuming you are using dlogin to get to the VMS system rather starting up
DECW$TERMINAL on the VMS system and pointing it back to your DS3100.  If not,
ignore the rest of this message.

The echoing of ^Z, ^C, ^Y as Exit, Cancel, and Interrupt is done locally
by the VMS
terminal driver.  Since you are dlogin'ing from ULTRIX, you don't have a
VMS terminal
to do the echoing for you so dlogin echo's ^Z, ^C, and ^Y and ^Z, ^C,
and ^Y as per
the CTERM spec.  This may get fixed in a future release.

If you mean command line recall and editing doesn't work, then those are
a known
problems in dlogin.  A patched version of dlogin which corrects those
problems has
been made available to the various CSCs.

dlogin doesn't currently parse 8-bit escape/control sequences properly.

Get the fixed dlogin from your CSC.
