The nrzi_en parameter specifies if Non Return to Zero Inverted (NRZI) encoding is to be used
by the DCE for transmit and receive data.
The nrzi_en parameters are:
nrzi_en
0 NRZI encoding and decoding disabled (default).
1 NRZI encoding and decoding enabled.
The syn1 parameter (0-255) specifies the octet value(s) to be used while performing
character-oriented framing. <syn1>=n specifies the 8 bit transparent subMode
synchronization sequence and idle transmission value. The default setting for syn1 is 255.
The syn2 parameter specifies the octet value(s) to be used while performing character-
oriented framing. <syn2>=0 specifies the16 bit synchronization sequences are not
supported. The value must be 0.
The +ESA settings are saved in NVRAM by the &W command.
+ESR Selective Repeat (LAPM SREJ) Control
This command controls the use of the selective repeat (SREJ) option in V.42 (if present in the
DCE).
The formats for AT+ESR are:
+ES+R?Returns current setting.
+ESR=Returns command range(s).
+ESR=<value>
The value parameters are:
Value
0 Do not use SREJ.
1 Use SREJ if available in remote DCE; continue without it if not
(default).

+ITF Transmitter Flow Control
This command allows the DTE to determine the input buffer size in the DCE for data on circuit
103 from the DTE, to control the thresholds used for flow control of such data, and to control
