Default 4
Determines whether the modem responds to dial tone and busy signals,
and how it displays result codes for CONNECT messages. When the
modem ignores dial tone, it waits for a time delay given by register S6
(default = 2 seconds) and then dials regardless of presence or absence of
dial tone; this is called blind dialling.
Examples

only OK, CONNECT, RING, NO CARRIER, ERROR
and NO ANSWER result codes. Connection is
established by blind dialling.

CARRIER, ERROR NO ANSWER, BUSY, and
CONNECT XXXX (XXXX= rate) result codes.
Connection is established by blind dialling.
