Thanks Alan and David,

I'll try to work with the Integrated System Console (linemode) since it 
looks a LOT easier and cleaner than RXLDEV (glad to see that all my old 
brain cells are not yet totally fried; I did remember part of the solution 
even if I could not find references during searches). 

Prior to the Integrated System Console it would have been nasty.  It would 
have been a lot easier if 3215 support was never dropped in the first 
place.  What a complete pity (ask anyone dealing with a 2nd level VM or OS 
system).

 Does anyone remember the technique?  
 
Melinda is on vacation -- must be tough being retired. 
 
The code is on one of the older VM Workshop tapes (I seem to remember the 
UKY one). It used RXLDEV to drive a virtual device and a whole lot of 
magic to determine what had changed in the virtual screen image she 
maintained from the LDEV, which was then fed to PROP like a proper 
operating system. It then responded using VINPUT. 
 
IBM occasionally wonders why VSE survives. It's because VSE doesn't do 
half-ass stuff like dropping linemode console support and actually tries 
to get along nicely with VM.
