It means the command is not compatible with the device in the current processing mode.



For examples,



1. the following command will get the "-SET-E-INVDEV" error in batch mode



$ set term/device=vt200 ! stdin is not a terminal



2. You can't change terminal characteristics after spooling the terminal device!



$ set dev/spool TTA0

$ set term/dev=t200 TTA0
