extra_w3sz.c

// program extra.c for Linrad
// This demo program displays the following information in the two upper lines
// on the Linrad 'receive mode' screens:
// -the selected frequency
// -the selected mode
// -the selected bandwith
// -the selected input device
// -the selected network-modes
// -the UTC date and time
//
//  Pierre/ON5GN
//
// UPDATE HISTORY
//   7 sept  2004  first version for linrad 01.24
//  23 may   2010  BASEB16 and BASEB24 network-modes added
//                 layout changes
//                 documentation updates
//  27 june  2010  input device information added
//  
// INSTALLATION
//
// To install under Linux for Linux:
//   download lirxx-xx.tbz and extract it to your linrad directory
//   rename extra.c to users_extra.c in your linrad directory 
//   run ./configure and  make xlinrad (or make linrad) from your linrad directory
// 
// To generate a windows version under Linux:
//   install mingw32 from Leif's website
//   download lirxx-xx.tbz and extract it to your linrad directory
//   rename extra.c to users_extra.c in your linrad directory 
//   run ./configure and  make linrad.exe from your linrad directory
//
// To generate a windows version under Windows:
//   Install mingw and nasm from Leif's website in the C:\MinGW  directory
//   Download lirxx-xx.zip and unpack the linrad sources in your linrad
//   directory
//   rename extra.c to users_extra.c in your linrad directory 
//   Start a MS-DOS Command Window on your computer: click the Windows Start
//   menu and enter the "cmd.exe" command into the run box
//   In the MS-DOS Command Window issue a "cd" command to your linrad
//   directory, followed by a "configure.exe" and "make.bat" command
//
