MAIN Command D - Doors.

This command takes you to the Door System.  "Doors" are applications
external to RBBS-PC that a SYSOP allows callers to run remotely.  RBBS-PC
acts as a "gateway" or "door" to other programs.

A "door" can be any application (i.e.  on-line product ordering, games,
data bases, BBS message utilities, etc.).

Some doors require ANSI screen support, so read any information about the
door carefully.  You may also find that door access is restricted for the
first few minutes of each session.  This is so you will use other RBBS-PC
features, such as reading and entering messages before you spend time in
the door.
