Thanks, I might have known that once upon a time, but it's been ages, and I don't fool with RT11 much anymore.

I have it. The stock systems have only two RL units (see the RT5.0 Installation Guide). So when you try to init units 2 or 3, the requests go to unit 0 and fail. (RT11 could give better error messages, but it doesn't.) This code snippet from the distributed sources confirms it: .IIF NDF DL$UN, DL$UN == 2 .IIF GT DL$UN-4, DL$UN == 4 .IIF LE DL$UN, DL$UN == 1 .IRP X,<\DL$UN> .SBTTL *** THIS HANDLER SUPPORTS X UNITS *** .ENDR You need to generate a custom system to get 4 units. /Bob On 12/21/2011 1:10 PM, Ken Hall wrote: > I'm just letting the emulator create the file.
