Guys, I might be wrong here, but I believe the bottom line is:

Hardware:

1.  A modem card will support EITHER modems or direct connect
terminals (or PC's).
2.  A direct connect card only supports terminals (or PC's)

Software  The appropriate Ldev's must be specified correctly in
SYSGEN and/or
          NMMGR.

That is how I think it works.
