):
Auto bauding: With the first AT command, the HELMHOLZ Modem 56k 4.1 recog-
nizes the baud rate and the format of the incoming data and configures itself ac-
cordingly. When the modem doesn’t receive AT commands but user data right
away, the last saved settings are kept.
If more data is available than what can be received by the modem, the handshake
will regulate the data flow.
