S113 - Calling Tone Control
Description
The value in this register determines whether calling tone is transmitted
during call origination. If calling tone is sent, it starts after dialing
is completed and continues until answer tone or carrier is detected from
the answering modem. Calling tones comply with the requirements of V.25.
Use of calling tone is regulated in certain countries. In countries where
calling tone is required, S113 is not implemented in the modem. That is,
if calling tone is turned on, then S113 always has value 1 and if the command
S113=0 is sent, then the modem returns OK but does not change the value.
Note: When a call is originated and V.34 modulation is desired, the
V.8 calling signal, CI, is not transmitted.
