(TO BE MODIFIED LATER...:)
Added the PTC-II remote control from forward file.
There are a lot of commands. They are special to the PTC-II. They allow a lot of parameters to be changed in the TNC, but mainly QSY and SCAN commands (a remote control of any transceiver is included in the PTC-II). Added the fequency-status information before connection In PACTOR, a frequency cannot be shared, only one qso at a time as one of the two connected stations is sending while the other is receiving. So there is a special procedure which is made before calling. The busy led has a time-out of three seconds, that is when it lights, it always stays on at least three seconds. This is the method : - wait 5 seconds a previous busy status to be eventually light off. - wait 10 seconds to be sure that nobody is sending - call the remote station Added the PTCTRX built-in program to pilot the transceiver from PTC-II The parameters are the same that the TRX command of the PTC-II ex : " X PTCTRX SCAN 1 " will start scanning from forward file PTCTRX looks like a QSY program (like ICOM) but in fact send commands to the TNC. The commands may be memory channels, frequencies or channels scanning. Packet ports of the PTC-II implemented. They are packet ports, only need to be declared as the attached example PTCTRX is a built-in program. The syntax is exactly the same as the TRX command of the PTC-II. This command is described as 6 pages in the documentation of the PTC, so better to say : discribed in the PTC-II documentation Added a scanning control command. Only PTC. It is an icon only displayed when pactor mode is available, also a pactor menu appears in the menu bar Forced disconnection if not disconnected after 10 sec. Only PTC. if the normal disconnection is not done, a forced disconnection is sent. ChangeOver button for pactor mode This button is only displayed if pactor mode is available. It allows to change from ISS (Send mode) to IRS mode (Receive mode). The pactor is not like in packet where the two connected stations may send and receive packets. In pactor one sends its packet until it decides to change the direction (changeover) and then it is in receive mode and the other is in send mode. I can say that it is like a phone qso where when you are speaking other is listening until you finish and givehim back the microphone. The change-over button is only to force a change, normally all is automatic.
