TTerm will connect to an IPv4 or IPv6 host addresses but is set to connect to IPv4 host addresses by default. To enable IPv6 support follow these steps:

  1. Create a new saved connection or edit an existing connection.
  2. Select the Comms item.
  3. Select the Connections Settings item. This item is the same for both Telnet and SSH.
  4. Set the Enable IPv6 item to On.

TTerm will now connect to the IPv6 host address entered into the Remote Host Address field.
