+EB - Break Handling in Error Control Operation
This extended-format compound parameter controls the break handling in V.42 operation. It
accepts three numeric subparameters:
Syntax
+EB=[<break_selection>[,<timed>[,<default_length>]]]
Defined Values
<break_selection> Decimal number 0 specifying that break is to be ignored, i.e., not
signaled to remote DCE.
<timed> Decimal number 0 specifying that any transmitted V.42 LSIGNAL
will not indicate break signal length
<default_length> Decimal number 0 specifying that break is not delivered to the DTE.
Reporting Current or Selected Values
Command: +EB?
Response: +EB: <break_selection>,<timed>,<default_length><CR>
Example: +EB: 0,0,0 For default settings.
Reporting Supported Range of Parameter Values
Command: +EB=?
Response: +EB: (<break_selection> range),(<timed> range), (default_length> range)
Example: +EB: (0),(0),(0)
+ESR - Selective Repeat
This extended-format numeric parameter controls the use of the selective repeat (SREJ) option in V.42.
Syntax
+ESR=[<value>].
Defined Values
<value> Decimal number 0 specifying that SREJ is not used.
Example:
+ESR:0 For default settings.
+EFCS - 32-bit Frame Check Sequence
This extended-format numeric parameter controls the use of the 16-bit or 32-bit frame check
sequence (FCS) option in V.42.
Syntax
+EFCS=[<value>]
Defined Values
<value> Decimal number 0 specifying the use of the 16-bit FCS specified in V.42.
Reporting Current or Selected Values
Command: +EFCS?
Response: +EFCS: <value>
Example: +EFCS: 0 For default setting.
