5.1.2 Save Configuration
If the modem configuration was adjusted to certain user requirements, these settings can be saved in the user profiles 0
or 1.
Configuration changes will be lost after a RESET or restart if they were not saved before.
5.2 Serial Data Transmission
5.2.1 Automatic Baud Rate Detection
The modem will automatically detect the baud rate of the connected PC.
The adjustment to the transmission speed on the phone line is performed automatically, unless the settings say otherwise. While a connection is established, both modems attempt to achieve the joint fastest speed on the phone line.
For an existing connection, the modem must first switch to command mode.
You will receive the transmission settings …
e.g.: +MS: V92,1,300,48000,300,56000
This means that a connection between 300 and 56000 bps was established, preferably according to V.92, depending on the line quality and the abilities of the remote terminal.

5.2.2 Data Buffer for Serial Data Transmission
The modem has a fast send and receive cache (so-called buffer) to adjust the modem to the PC operating speed. It is, however, possible to deactivate this data buffering and switch to bit direct mode.
When working with buffers, handshake must be used, because otherwise an overflow could occur which might lead to data transmission errors.
5.2.3 Bit Direct Mode
Only for special, non-standard data formats
In bit direct mode, the modem has no influence on the transmission format. The data is transmitted without buffering.
Data compression or error correction will not work in bit direct mode. Only the abort sequence - default +++ - is utilized by the modem.
5.2.4 Hardware Data Flow Control with RTS/CTS
Hardware Data Flow Control with the Modem (CTS).
Modem
RS232 Cable
CTS Line
PC or control
When the input buffer of the modem exceeds a certain fill state, the modem will set the CTS line to OFF. This will indicate to the modem not to send any more data.
After the modem has operated the input buffer so far that the XON buffer falls below a certain fill state, it switches the CTS line on and reports to the PC that it is ready to receive data again.

PC or control
The PC sets the RTS line to OFF to request the modem to interrupt the data transmission.
It will depend on the according PC software, if the RTS/CTS lines are operated from the PC.
The PC sets the RTS line to ON to request data from the modem.
5.2.6 Software Data Flow Control XON and XOFF
Modem
Send data
XON or XOFF character
PC or control
When the input buffer of the modem exceeds a certain fill state, the modem will insert an XOFF character into the data stream to the PC. This character will cause the PC to send no more data.
If the PC supports XON/XOFF data flow control will depend on the
according PC software. After the modem has processed the input buffer so far, it will insert
a XON character into the data stream. This character will cause the PC to send data again. Analogously, the PC can control the data stream from the modem to the PC.
The XON/XOFF method is only available when the transmitted data do not contain the characters XON or XOFF, which usually means only in actual ASCII texts (7 bit). When binary data (programs, etc.) are transmitted, also for BTX operation or in the XMODEM transmission protocol, for example, occasionally appearing XON or XOFF characters would disturb the operation.

5.2.7 Reset
There are two reset options:
¾ A reset is performed after the power supply has been interrupted for a
short time.
¾ With the help of the terminal program
After the software reset, load the user profile 0
After the software reset, load the user profile 1
5.2.8 Dial-up Delay
According to the TBR 21 regulations, after 12 futile dial-up attempts each further dial-up is locked within 2 hours. In this case, the modem must be temporarily switched off.
The counter is automatically reset after each successfully established connection.
After the connection has been established, a dial delay of 5 seconds is observed.
5.3 Error Correction
The modem masters the V.42 error correction protocol including the Microcom Networking Protocol Levels 2/3/4 (MNP2, MNP3, MNP4) and the data throughput optimization MNP10.
5.3.1 V42 Error Correction
The V.42 error correction includes the protocols LAPM (Link Access Procedure for Modem) and MNP 4. LAPM is the preferred error correction.
MNP 4 is supported for compatibility reasons with other MNP modems. Both methods determine frames to transfer net data and use CRC (Cyclic Redundancy Check) check sums for error tests.
In V.42, the possibility exists to have the modem identify if the partner is a V.42 modem, a MNP modem, or a modem without error correction. The modem can then autonomously adjust to the partner.
ATZ0 ATZ
ATZ1
Pocket Modem 56k Function
5.3.2 MNP 2/3/4 Error Correction
The MNP error correction can be operated either in block or in stream mode. The maximum block size can be set to either
64 byte 128 byte 192 byte and 256 byte.
The MNP error correction can either be set automatically or activated via AT commands.
5.4 Data Compression
The modem will identify the type of data compression used by the other modem, or it is fixed on a certain type or no data compression.
Data compression is only available for error corrected connections.
To be able to use data compression, both sides (sender and recipient) must be able to recognize the same data compression mode.
5.4.1 V.42bis Data Compression
Switch on V.42bis data compression
Switch off V.42bis data compression
V.42bis data compression may only be performed for a V.42 connection (LAP-M or MNP 4). First of all, V.42bis generates a so­called dictionary for the data compression, which contains frequently used character sequences. After that, only short references to these character sequences and not the complete character sequences are transmitted to the other modem.
V.42bis cannot re-pack packed data.

5.4.2 MNP 5 Data Compression
The modem masters the Microcom Networking Protocol Level 5. MNP 5 data compression can only be performed for an error corrected MNP 4 connection. MNP 5 replaces frequently used characters by shorter characters, so-called tokens.
MNP 5 cannot re-pack packed data.
5.4.3 V.44 Data Compression
The V44 data compression offers better compression of typical Internet content than V.42bis. V.44 also requires an error corrected connected, just as V.42bis, and cannot re-compress already compressed data.

5.5 Selective Call Answer
If the selective call acceptance is activated, the modem will only accept calls from certain callers. The identification of permitted callers takes places via the caller ID transmission (CLIP). This must, however, be supported by the phone system or the exchange connection, where the modem is connected to.
Activate the selective call acceptance
Deactivate the selective call acceptance
Display a complete list of saved phone numbers for the selective call answer
Delete the complete phone list for the selective call acceptance
The list of phone numbers has 8 storage locations altogether (N0 to N7). Only if the transmitted phone number matches a phone number that was entered in the list will the modem accept the call according to the settings.
e.g.: Store phone number 1234 at storage location 6
The memory N<n> accepts all phone numbers ending in <nl>.
Our first example activates all phone numbers ending in 941586920.
The following phone numbers are activated: 0941586920, 0049586920 and +49941586920

5.8.3.2 Operation
Establishing a connection to the modem.
The connection to the modem is established. The modem responds to an incoming call, so after 2 seconds the message “REMOTE PASSWORD” is displayed.
You must now enter the “Remote Password”, which is identical with the password for the remote configuration.
After the password has been entered correctly, the modem hangs up and after about 10 seconds dials the stored phone number. Altogether, 3 dialing attempts with a pause of 10 seconds between each attempt are performed.
If the entered password was incorrect, the connection is terminated and thus prevents unauthorized access to the connected device.
After that, a normal data connection is established.
