V.34 Low Speed Transmit Rate Selection
(S53)
This register allows the bit rates of V.34 to be independently enabled and disabled. To turn
off V.34, set S53 and S54 to 0.
(Default):
255
Bit 0 =
2400 bps
Bit 1 =
4800 bps
Bit 2 =
7200 bps
Bit 3 =
9600 bps
Bit 4 =
12000 bps
Bit 5 =
14400 bps
Bit 6 =
16800 bps
Bit 7 =
19200 bps
V.34 High Speed Transmit Rate Selection
(S54)
This register is an extension of register S53. If the bit corresponding to a certain line speed is
set in this register, then that speed may be used for connections with V.34 modems. The
actual transmit speed negotiated is the highest of the selected speeds that both modems can
support under current line conditions. The speeds selected in this register will be attempted
first.
(Default):
