actual value of the received character the instrument determines the baud rate of the host PC and resets
its baud rate to match. It then sends the discovered baud rate to the host PC.
The instrument can be forced to the Autobaud state at any time by sending a com break. A com break is
an empty bit frame. The instrument contains circuitry that detects this event and forces a hardware reset
of the instrument. This allows the application software to reset the instrument to a known state.

When you end the session, HyperTerminal asks you if you want to save your settings. To avoid re-
entering the communication parameters, save them by clicking yes. The next time you execute the string

the session name opens the connection using the saved settings. To avoid re-entering the string of
