Hello ,
  Sincere thanks to Bruce Hines & Johan Brusche for
the solution.
  
  Problem :
  On a DS20 with Tru64 V4.0F, whenever the number of
users logging in
  via telnet exceeded 32, further connections were
refused with the
  user getting the message "port not available"/ all
ports in use.
 
  solution:
  As per instructions in the man page , i had created
used the
   MAKEDEV PTY_1 and MAKEDEV PTY_2 commands to create
additional
   ptys for use by the additional users .
   The correct method was to create additional ptys
using :
     ./MAKEDEV pty2 pty3
  existing ptys were from ptyp0 to ptypf and ptyq0 to 
    ptyqf a total of 32 ptys .
   MAKEDEV pty2 pty3 created additional 32 devices,   
    i.e. ptyr0 to ptyrf and ptys0 to ptysf.
   In addition to this the maxusers parameter in      
   /etc/sysconfigtab must
   be 128 or 256 .
   A simple reboot is reqd after above modifications.
 
   thanks & regards
   Dominic
