Generate Data Modem Calling Tone
This command allows the DTE to select whether the modem will send 1300 Hz
calling tone when originating a Data Modem connection.
-C0
Calling tone disabled. (default)
-C1
Calling tone enabled.
-Jn
Set V.42 Detect Phase
In V.42 modes (\N3, \N4), this command specifies whether the modem will detect
V.42, MNP, or no error-correcting protocols from the remote modem and change
to the appropriate mode. Otherwise, only LAPM will be attempted.
-J0
Disables the V.42 detect phase.
-J1
Enables the V.42 detect phase. (default)
“Hn
V.42 bis Compression Control
This command specifies whether the data in the LAPM frames are compressed
using the V.42 bis data compression, which can improve throughput by as much as
400%.
Compression can be negotiated to operate in only one direction, or in both
directions.
