Table 10: TCP/IP Port Numbers
Client application software can send raw data to COM1, COM2, PRN1, or
PRN2 by opening a socket to the associated TCP port number. Such connec-
tions are queued along with LPD and rsh/rcmd/remsh print jobs so that appli-
cations must close the socket to permit subsequent jobs that are queued to print
by other methods.
There can be 256 simultaneous TCP connections depending on the current
memory available. 10 simultaneous TELNET connections are possible.
