AT\B<n>
Send “break” to the other modem
For connections that were not error corrected the modem sends a break signal to the
other modem. The length of the signal is: the specified parameter times 1/10 of a sec-
ond.
For error corrected connections, the modem sends a break signal according to the ac-
tive error correction protocol without considering a parameter specification.
If no connection is established or if a fax connection is active, an error message is dis-
played.
