I've been seeing a lot of these lately (on my PC, running r1win 5.10):
------example------------
:nmmgr
<at least 20 sec delay>
Terminal is of incorrect type or cannot be opened.  (NMGRERR 1))
The terminal status request failed.
:?008000
Invalid first character in command name. (CIERR 9090)).
:
---------end example--------------
R1win (connected with NS/VT) says the terminal is set to HP2392A, when I
do
:input termid;wait=2;prompt="![chr(27)]*s^"
the terminal respons is '2392A'. It has happened with homegrown (VPlus)
apps as well as NMMGR (although the output is a bit different). I
understand this is related to VPLUS(?), but is the error in VPLUS
(nah..) or Reflection, and does anyone know what causes it? Also, the
command '?008000' that gets 'executed' just after the abort (it shows up
on the redo-stack), just what is it? terminal respons to some other kind
of status request vplus does?
clues? anyone?

TIA
/per

btw
The :input termid;wait=2;prompt="![chr(27)]*s^"-trick was contributed by
someone on this list some time ago, thanks a lot! (sorry, can't remember
who). Just shows how valueable this list is...
