How to Send Control Codes in a Hyperterminal
The HyperTerminal program was used to connect to other computers, bulletin board systems, Telnet sites, online services and host computers. HyperTerminal was primarily used in the era before widespread use of the Internet. Still, HyperTerminal may still used to monitor messages that are sent to and from the computer, since the HyperTerminal records sent messages, allowing you to see whether the HyperTerminal is connecting correctly and whether the settings are correct. To do so, you send commands through the HyperTerminal and check the results.

Tips & Warnings
When you leave the HyperTerminal, you will receive a message that asks you to save the settings. Click “yes” and you will automatically be set up to access HyperTerminal in the future, without having to go through the steps to set it up.
If you have a 56k modem, set the Bits per second to 57,600 or 115,200.
Unlike other codes, the +++ codes do not appear in the HyperTerminal after you type them, but that doesn’t mean they didn’t go through.
