TTYLINK Question

It is possible to connect to the mailbox by AX.25 or telnet and issue
the sysop ("@") command.  If the proper bit mask is set in the FTPUSERS
file so that the user has sysop privileges, this command gives remote
access to the "net>" prompt.  It is then legal to make routing changes,
start and stop processes, and so forth, as long as the commands issued
by the remote sysop do not start a session.  In other words, everything
except "ftp" and the like are legal.  (Shelling out is also, obviously,
illegal.)

Do you really want a remote user to have to capability to send raw data
directly to an interface?  This starts to get far afield of what most
people do with NOS.  I can see it from the local console, since the
code to do it is trivial, but anyone who has tried to write a "door"
in the landline BBS world will quickly appreciate the problem of having
a whole new "raw interface" server.
