The rig control daemon (rigctld) is part of Hamlib. It provides a way to control \
various rigs using CAT commands, usually over a serial port.\n\nIn order to set up \
aliases (shortcuts) in the pat web interface for RMS Gateway stations ALONG WITH \
their frequency, pat requires the use of rigctld. When started, the GUI you're \
currently using will check to see if rigctld is already running. If it's not, it'll \
start rigctld using a 'dummy' rig, which fools pat into thinking it's controlling a \
radio when it's not (meaning you have to set your radio's frequency manually).\n\nIf \
your rig is supported by Hamlib (or to check to see if it is supported), click the \
'Manage Hamlib rigctld' button below to have the TNC and pat REALLY talk to your \
radio (if supported) and have pat automatically QSY as needed."
