At the keyboard
While DIGI_NED is running you can use:
- ALT-X to exit the program.
- ALT-V toggles the 'verbose' mode on and off.
- ALT-D can shell you to dos using (only for DOS and only when the COMSPEC environment variable is set correctly).
- ALT-B forces Beacons to be transmitted.
On the keyboard you can also do the same queries as you can do via APRS messages. So if you type "help" you will get the help text... If you are running in verbose-mode than you can switch that off with ALT-V to be able to see the responses. When finished you can switch verbose mode on again with ALT-V.
When you are logging to a logfile then you can stop logging with ALT-L. The logfile will be closed so you can shell to DOS to remove or rename it without a problem. When hitting ALT-L gain the logging will restart, new data will be append to the existing logfile. When stopping and starting a timestamp and a visible separator is written to the logfile.
The same function as for the logfile also exists for the TNC logfile, this is a logfile in 'tnc' format that can be read by other programs too. To toggle the file off and on use ALT-T (T for TNC...).
With the "-a" flag you can switch on activity display to see who is sending queries to the digi. You can switch this on and off by the keyboard also using ALT-A (A for Activity).
If you can't remember all the keystrokes just remember one simple one, ALT-H. ALT-H will give you a list of all key combinations that are possible in either DOS or Linux.
Under Linux this all doesn't work unless you sepecify the '-k' flag at the commandline. The implementation is restricted with respect to terminal types, for example backspace only works when it uses ASCII code 0x08. On my RedHat 5.2 system you can use the ALT- combination.
If that doesn't work on your system you may press ESC followed by the desired letter instead, e.g. press and release ESC followed by a press and release of H gives you the keyboard help.
Under Linux you cannot use ALT-D to start a shell, use a different virtual console or different Xterm window instead! You don't realy need the keyboard commands in Linux since you can run may things simultaneously anyway and you can do queries through an internal loopback connection with XASTIR for example (that's how I test my stuff also). I found it however convinient during testing of the queries and the satellite support since it works much faster then commands via the loopback or via RF.
