New connection ([File] menu)

Connects to a new host or a serial port. If the connection is already open, opens a new Tera Term window.

"New connection" dialog box

TCP/IP

Host
Enter the host name or IP address, or select one from the host list. To edit the host list, use the [Setup] TCP/IP command. You can enter not only the host name or address, but also the command line parameters like the following:
    myhost.mydomain                     Host name only.
    myhost.mydomain:23                  Host name with a port number.
    foohost.foodomain /F=FOOHOST.INI    Host name & setup file name.
    /C=1                                Specifies the serial port connection.
    /R=LOG.DAT                          Replays the log file.
    
Telnet
Enables the telnet protocol. Usually, you should select this option.
TCP port#
Normally, you should use the TCP port number 23 for the telnet protocol.

Note:
Only if <telnet flag> is on and <TCP port#> is 23, Tera Term starts spontaneously sending telnet commands to the host for the option negotiation when the TCP/IP connection is established. In any cases, Tera Term can respond to telnet commands sent by the host.
