2.2.2 Register Write Command
The register command can also be used to write a value to the register on the current active device (NN).
Syntax
FXOCTL:NN> register rgXX=0xYY
Where: XX 00 to 25 hexadecimal represent the registers from 00 to 25 hex.
YY Hexadecimal value from 0x00 to 0xFF.
NN Shows the current active channel ID.
Refer to the chip datasheet for registers, their usage and contents. The following is a log of the command
to write register 0x12 with the value of 0xC0.

2.3 Answering of Incoming Calls
The FXOCTL reports incoming RING event when one is detected. Each FXO channel can be
programmed for auto answer mode to automatically answer the call, or manually answered by the user
using this “answer” command.
2.3.1 Auto Answer Setting Command
The autoanswer command sets auto answer mode to the channel. In this mode the incoming call on
the FXO channel will be automatically answered by the FXOCTL program. This is accomplished by
bringing the channel off-hook when incoming ring is detected without user intervention.
Syntax
FXOCTL:NN> autoanswer (set auto-answer mode on current active channel)
FXOCTL:NN> autoanswer <XX> (set auto-answer mode on channel XX)
Where: XX 00 to 15 decimal represents the device ID.
NN Shows the current active channel ID.
The following is a log of the command to set auto answer mode on current active channel (0) and on
channel 3.
