+EB Break Handling in Error Control Operation
This command controls how break signal is handled. Operation mode for a break
signal to be sent to remote end is selected with <break-sel>, and <timed> specifies if
break length is signalled to the remote end. Default length of a break signal to be
sent to local DTE is specified with <def-length> for the cases where break length is
not received. These settings are only used in transparent data call (see command
+CBST at page 14) with V.42 enabled (see cES at page 53). (V.25ter)

AT+EB=[<break-sel>[,
<timed>[,<def-length>]]]

Default options
are 1, 0, 30.
