<max_codewords_tx> The decimal number from 256 to 2048 that specifies the
<max_codewords_rx> The decimal number from 256 to 2048 that specifies the
<max_string_tx> The decimal number from 32 to 255 (maximum string length).
Break Handling in Error Control Operation
This extended-format compound parameter controls the break handling in V.42 operation.
It accepts three numeric subparameters:
+EB=[<break_selection>[,<timed>[,<default_length>]]]
<break_seleIction> Decimal number 0 specifying that break is to be ignored; i.e., not
<timed>
<default_length>
+EB?
+EB=?
This extended-format numeric parameter controls the use of the 16-bit or 32-bit frame
check sequence (FCS) option in V.42.
<value>
+EFCS?
+EFCS=?
Error Control Reporting
This extended-format numeric parameter controls whether or not the intermediate result
code is transmitted from the modem to the DTE.
S95 bit 3 is reset to 0 for +ER=0 and is set to a 1 for +ER=1. The more recent setting
of+ER or S95 bit 3, and the W command setting, determines the actual error control result
code reporting (see S95 Parameter and W Command).
0, 1
0 = Error control reporting disabled (no +ER intermediate result code transmitted).
1 = Error control reporting enabled (+ER intermediate result code transmitted).
0
+ER?
+ER=?
Error Control Selection
This extended-format command specifies the initial requested mode of operation when the
modem is operating as the originator, optionally specifies the acceptable fallback mode of
operation when the modem is operating as the originator, and optionally specifies the
acceptable fallback mode of operation when the modem is operating as the answerer.
It accepts three numeric subparameters:
+ES=[<orig_rqst>[,<orig_fbk>[,<ans_fbk>]]]
<orig_rqst> Decimal number which specifies the initial requested mode of operation

direction. Default = 2048
maximum number of code words which should be negotiated in the receive
direction. Default = 2048

Decimal number 0 specifying that any transmitted V.42 L-SIGNAL
will not indicate break signal length.
Decimal number 0 specifying that break is not delivered to the DTE.
