INSYS Modem 336 LL 2D/4D 5.x Originate / Answer Functions
12.1.2 Phone connection
The automatic negotiation of the baud rate and the modulation standard enables the
INSYS Modem 336 LL 2D/4D 5.x Originate / Answer to negotiate the largest possible
connection speed to the remote terminal while the connection is established. The speed
depends on the settings and the abilities of the modem at the remote terminal. Via the
modulation standard, the connection speed can be set through the phone line. If nothing
is defined, the INSYS Modem 336 LL 2D/4D 5.x Originate / Answer will automatically try
to determine the optimum connection parameters.
The function is active as default.
Configuration with AT commands
To configure the modulation standard and
thus the connection speed, use the command
AT+MS=<modulation>
Please find the possible parameters for this command in the Chapter "AT
Command reference".
To display the current settings

Answer can be deactivated using the setting "unbuffered, bit direct". All data is for-
warded without buffering and further influence of the INSYS Modem 336 LL 2D/4D 5.x
Originate / Answer. This applies especially to the parity and stop bits. The error correc-
tion and the data compression are in this case switched off as well. If the INSYS Modem
