fnet - command line control for Fohhn DSP devices
SYNOPSIS
fnet -t tty -d id -gc command [-p parameters]
fnet -t tty -d id -sc command -p parameters
DESCRIPTION
Command line utility to control Fohhn DSP devices over a serial port or
udp node. Alle values are written without delimiter, for example for
-20.5dB write -205.
Most devices use the default serial port speed of 19200 baud only.
Devices released 2023 and later use 115200 baud over the usb port.
Devices released 2023 and later have no support for the relative
volume command, that is used for the dedicated mute command.
Use the absolute volume command for volume and mute instead.
OPTIONS
-t serial device
-b baud rate
