- I think the special is for DTC/telnet connections.  In order to have the
  ADCP/AFCP protocol to signal to telnet on the DTC that the TCP connection
  should be killed, ADCP drops the 'modem signals'.  With this piece of
  information the DTC telnet knows when the HP3000 host wants to close the
  TCP connection (i.e. BYE, ABORTJOB). I guess someone from termio will
  correct me if I'm wrong.

- Not quite.  There's also the NS services default "number of servers of
  each type" and total number of servers.  By default NS allows #300 vtservers
  on the system and this value can be adjusted up and down with
 
    NSCONTROL SERVER=VTSERVER,min,max
 
  command.  Max total number of servers is #1250.
 
: NMMGR (note that other things use TCP connections too).  Telnet sessions and
: non-nailed DTC sessions (sum of the two) limited by "max number of non-nailed
: ldevs".  Telnet sessions (from the DTC) do not count as a TCP connection.
 
- Right.  Telnet comes in as a DTC terminal using AFCP/ADCP protocol - no TCP.
