IP version

Selects as an IP version from AUTO or IPv6 or IPv4.
The AUTO try to connect to the IP address associated with the hostname.
Either IPv6 or IPv4 using depends on the OS setting(priority of IP version).

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.
