+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 Value
<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 L-
SIGNAL will not indicate break signal length
<default_length> Decimal number 0 specifying that break is not delivered to the
DTE.
