When using a Serial connection, there are several ways to send a break-line condition.
• If the VT220 keymap is selected, you can use the F5 key.
• When using any of the keymappings supplied with SecureCRT, you can generate a break by using the CTRL plus PAUSE/BREAK key combination.
• You can also use the Button Bar or Keymap Editor to arbitrarily map the Telnet function TN_BREAK to a button or to any key you like.
