Quisk and other SDR programs in Linux are using rigctl commands emulating a rigctld server on port 4532 I am able to write an entry in VarAC_cat_commands.ini but VarAC is sending commands without a '\n' terminator (LF) and [RET] send a '\r' (CR), not a '\n'. This is my entry: [Rigctl 4532] CmdType=TEXT PTTOn=T 1 PTTOff=T 0 ModeUSB=MD2; ModeUSB_D=M PKTUSB 2700 ModeFM=MD4; SetFreq_Data_method=TEXT SetFreqVfoA_Cmd=F {} SetFreqVfoA_param_length=8 SetFreqVfoA_hz_res=1 ReadFreqVfoA_Cmd=f ReadFreqVfoA_Result_Data_method=TEXT ReadFreqVfoA_Result_hz_res=1 ReadFreqVfoA_Result_Length=8 ReadFreqVfoA_Result_Freq_Start_Pos=1 ReadFreqVfoA_Result_Freq_Length=8 VarACStartCmd= VarACExitCmd= Adding a '\n' at end of each command send a '\\n' How can I add a LF character to the end of each command?
