The Port Server and Rotaries
The user can return to the CLI and issue the fg command to access the Telnet session. At this point,
the user is connected to the modem and can use a dial command. For example:
annex: jobs
+1 rlogin HostB
-2 telnet 5390_01 &
annex: fg 2
2 telnet 5390_01
ATD...
By creating rotary entries in the configuration file, you can force camp-on without questioning the
user or disable camp-on entirely (see Rotaries on page A4-9 and Parsing the Configuration File
starting on page A14-3).
Defining TCP Port Numbers
telnet and rlogin can include a TCP port number in the connection request. The Model 5390 server
recognizes the following ranges of TCP port numbers for telnet and rlogin connections: 5000, 6000,
and 7000. (The Model 5390 server recognizes TCP port numbers in the 9000 range for TSTTY
connections (for more details, see Configuring the Model 5390 Server for TSTTY starting on page
A4-21)).
The port numbers in both the 5000 and 7000 range map directly to serial ports: TCP port 5001 maps
to serial port 1, TCP port 5002 maps to serial port 2, TCP port 7001 maps to serial port 1, etc. (it is
not necessary to configure these TCP ports).
TCP ports in the 5000 range connect directly to the specified serial port using telnet or rlogin. The result
is the same as selecting the serial port through the port server, but there is no negotiation or camp-on.
The connection is refused if the serial port is busy or not in slave or adaptive mode.
NOTE:
A special version of rlogin, one that accepts TCP port numbers,
is needed to use TCP port numbers with rlogin.
