When bit 7 of S53 is set, this register controls the length of time (in seconds) that
the modem will wait before starting to dial after going off-hook when blind dialing.
This register is used for the countries where the wait for dial tone delay (S6) can
be set differently from blind dialing delay.
Register S91 specifies the line transmit level in dBm with an implied minus sign.
Range: 6—25 (corresponding to –6 dBm to –25 dBm transmit level).
Default: 10 (–10 dBm transmit level).
Base Units: –dBm transmit level.
Sets the transmit attenuation level from 6 to 25 dBm for the FAX mode, resulting
in a transmit level from –6 dBM to –25 dBm.
Range: 6 dBm to 25 dBm (corresponding to –6 to –25 dBm transmit
level).
Default: 10 (–10 dBm transmit level).
Base Unit: –1 dBm transmit level.
This register has a dual purpose:
1 When S94 is set to zero, this register controls the overall DTMF transmit
level, with the twist between DTMF groups fixed at 2 dB.
2 When S94 is set to a nonzero value, this register controls the transmit
level for low DTMF group only.
Range: 5 to 25 dBm (corresponding to –5 to –25 dBm transmit level).
S48 = 7
Do not use.
