Enabling Synchronous Access Mode enables the use of the 8-bit command characters defined in Table 9/V. 80 of the Draft ITU-T Recommendation V. 80 (DATA COMMUNICATION OVER THE TELEPHONE NETWORK; In-Band modem Control and Synchronous Data Modes for Asynchronous DTE). Syntax +ESA=[<trans_idle>[, <framed_idle>[, <framed_un_ov>[, <hd_auto>[, <crc_type> [, <nrzi_en>[, <syn1>[, <syn2>]]]]]]]] Defined Values <trans_idle> Decimal number which specifies the bit sequence transmitted by the modem when a transmit data buffer underrun condition occurs, while operating in Transparent sub-Mode. The options are: 0 In Transparent sub-Mode, modem transmits 8-bit SYN sequence on idle. Modem receiver does not hunt for synchronization sequence (default and fixed). <framed_idle> Decimal number which specifies the bit sequence transmitted by the modem when a transmit data buffer underrun condition occurs immediately after a flag, while operating in Framed sub-Mode. The options are: 0 In Framed sub-Mode, modem transmits HDLC flags on idle (default and fixed). <framed_un_ov> Decimal number which specifies the actions undertaken by the modem when a transmit data buffer underrun or overrun condition occurs immediately after a non-flag octet, while operating in Framed sub-Mode. 0 1 In Framed sub-Mode, modem transmits abort on underrun in middle of frame. (Default. ) In Framed sub-Mode, modem transmits a flag on underrun in middle of frame, and notifies DTE of underrun or overrun. <hd_auto> Decimal number which specifies whether or not, in V. 34 halfduplex operation, additional procedures besides those specified in § 12/V. 34 will be performed by the modem when switching from primary channel to secondary channel operation, and vice versa. This subparameter should not be commanded. Decimal number which specifies the CRC polynomial used while operating in Framed sub-Mode. The options are: 0 CRC generation and checking disabled. (Default and fixed. ) <crc_type> 3-52 Conexant 100498E Commands for Host-Processed Modems Reference Manual <nrzi_en> Decimal number which specifies if Non Return to Zero Inverted (NRZI) encoding is to be used by the modem for transmit and receive data. The options are: 0 <syn1>, <syn2> NZRI encoding and decoding disabled (default and fixed). Decimal number which specifies the octet value(s) to be used while performing character-oriented framing. <syn1> is to be commanded to 255 (FFh); <syn2> is not to be commanded.

Reporting Supported Range of Parameter Values Command: +ESA=?Response: +ESA: (<trans_idle> range), (<framed_idle> range), (<framed_un_ov> range), (<hd_auto> range), (<crc_type> range), (<nrzi_en> range), (<syn1> range), (<syn2> range) +ESA: (0), (0), (0-1), , (0), (0), (255) Example: 100498E Conexant 3-53 Commands for Host-Processed Modems Reference Manual +ITF - Transmit Flow Control Thresholds In V. 80 Synchronous Access Mode, this optional compound parameter allows the DTE to determine the effective input buffer size in the modem for data on transmit data from the DTE, to control the thresholds used for flow control of such data, and to control how often the modem reports to the DTE the number of octets in this buffer. Note that the DTE can adjust its own thresholds for flow control of data on received data from the modem. Syntax +ITF=[<off>[, <on>[, <report_period>]]] Defined Values <off> Determines the threshold, in octets, above which the modem will generate a flow off signal. For the <on> and <off> subparameters, the input buffer is assumed to reside between the modem's V. 24 interface and the Synchronous Access protocol layer; i. e. , the buffer count includes all octets, including EM codes, received from the DTE, with the exception of XON and XOFF if these are used to signal <modemby-DTE> flow control. The modem returns the ERROR result code if the DTE specifies that the <off> subparameter be set to a value less than or equal to the <on> subparameter; in this case, the current parameter value settings are set to default values. <on> Determines the threshold, in octets, below which the modem will generate a flow on signal.
