Description
Delay between lost carrier and hang up. S-
register S10 specifies the time between the loss
of the CARRIER signal from the other modem
and hang up by this modem. The carrier signal
may be lost for periods up to the value of S10
minus the value of S9 without causing the modem
to hang up. Setting S-register S10 to 255
disables hang up of the telephone line because of
the loss of a CARRIER signal.
The modem only recognizes a CARRIER signal
after the time specified in S-register S9 . The
value of S-register S10 should always be greater
than the value of S-register S9 so a CARRIER
signal can be recognized before the telephone line
is hung up.
Multi-Frequency tone duration. S-register S11
specifies the duration of a DTMF tone.
Depending upon the country configuration, S11
may also specify the time between DTMF tones.
Escape prompt delay time. S-register S12 spec-
ifies the prompt-delay time for escape sequences
from the ON-LINE state to the COMMAND
state.

Sets transmit level. S-register S17 specifies the
actual transmit power. This value is adjusted by
the country configuration to accommodate differ-
ences in transformers and other components in the
telephone line interface.
