hexadecimal notation. No entries can be made in the right-hand box. In the left-hand box,
a string can only be entered when either no entry can be found for the current
combination of modem and network parameters in the SINAUT modem database or the
User defined option was set. Otherwise the valid string is taken from the database.

It allows the manual entry of AT Initialization strings for the basic settings of the modem.

Special features of the MD4 modem
On the MD4 modem, the standard string is ATS45=83$P1\N0&W$M=n .
The part string
$P1 defines the V.110 mode at a transmission rate of 9600 bauds.
The
n character at the end of the string is the placeholder for the MSN (last digit of the
telephone number) of the subscriber.
The stored standard string allows only transmission rates of 9600 and 19200 bauds, no other
rates are not supported. This standard setting does, however, allow communication with the
following subscribers:
● Old ISDN modems installed with SINAUT ST1 devices
● GSM stations
● SMS centers
