Skycatd Commands

skycatd understands the following TCP commands, followed by the NewLine character:

Action	Command
setup(Duplex)	U Duplex
setup(Split)	U Split
setup(Simplex)	U Simplex
read_rx_frequency	f
read_tx_frequency	i
write_rx_frequency	F {frequency}
write_tx_frequency	I {frequency}
write_rx_mode	M {mode} 0
write_tx_mode	X {mode} 0
read_ptt	t
set_ptt_on	T 1
set_ptt_off	T 0

where frequency is the frequency in Hertz, and mode is a mode name, e.g., CW.

For compatibility with rigctld.exe, the ‘U SATMODE 1’, ‘S 1 VFOB’ and ‘S 0 VFOB’ commands are recognized as aliases of the Duplex, Split and Simplex setup commands respectively.
