   4         This code was mainly put together by looking at the
   5         following programs:
   6
   7         asclock
   8                 A neat piece of equip, used to display the date
   9                 and time on the screen.
  10                 Comes with every WindowMaker installation.

  15                         How do I use pixmaps?
  16
  17         pppstats
  18                 A program that prints the amount of data that
  19                 is transferred over a ppp-line.

  59                 * Added:
  60                         Speed-O-Meter (after 60 seconds)
  61                         Fixed Error reporting when pressing X
  62                         Removed the ugly kb lines
  63                         Stopped clearing on-line time when pressing X
  64                         Added createXBMfromXPM
  65         08/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  66                 * Removed some code from get_statistics
  67                 * Check if "ifdown" is empty before execCommanding it!
  68         07/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  69                 * Made the program use the xpm like warp wanted it to be :)
  70         04/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  71                 * Added pppX support. (EXPERIMENTAL!)
  72                   Removed HARD_CODED_DEV. (that stayed in long! :) )
  73                 * Changed 33600 speed indication to 33k6
  74                   Bugs if larger than 115k2 (depends on how much 1's present)
  75                   Moved the speed ind. code to DrawSpeedInd
  76                 * Added 1k lines in the stats
  77                 * Moved all the "ppp0" references into HARD_CODED_DEV.
  78                   for easy change
  79         03/05/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  80                 * Removed the number after -t.

  84                 * Added some extra checks for the -t option.
  85                   If no number was given, it would core dump
  86         30/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  87                 * Added execCommand code. (taken from windowmaker soure, as advised by Marcelo E. Magallon)
  88                 * Cleaned the source up a bit
  89                 * Decided to split op wmppp and wmifs
  90                   This is gonna be wmppp
  91                 * Used the DrawStats routine from wmifs in wmppp
  92                 * I decided to add a list in this source file
  93                   with name of ppl who helped me build this code better.
  94                 * I finally removed the /proc/net/route dependency
  95                   All of the connections are taken from /proc/net/dev.
  96                   /proc/net/route is still used for checking if it is on-line.
  97         27/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
  98                 * WMIFS: stats scrolled, while red led burning
  99                 * WMPPP: changed positions of line speed
 100         25/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 101                 * Changed the checknetdevs routine, a lot!
 102         23/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 103                 * Added line speed detection. via separate exec. (this has to be suid root!)
 104                   Speed has to be no more than 99999
 105                 * Added speed and forcespeed in ~/.wmppprc and /etc/wmppprc
 106                 * wmifs: added on-line detection scheme, update the bitmap coordinates
 107                 * wmppp: the x-button now allways disconnects.
 108         22/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 109                 * Added /etc/wmppprc support, including "forced" mode.
 110                 * Added /etc/wmifsrc support, including "forced" mode.
 111         21/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 112                 * Moved the stats one pixel down.
 113                 * Added status led in wmifs.
 114                 * Changed RX/TX leds of wmifs to resemble wmppp
 115                 * Added the "dot" between eth.0 ppp.0 etc.
 116                 * Changed to wmifs stats to match wmppp stats (only pppX changed)
 117                 * Made sure that when specified -t 1, it stayed that way, even
 118                   when longer than 100 minutes online
 119                 * With -t 1, jump from 59:59 to 01:00 instead of 99:59 to 01:40
 120         16/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 121                 * Added "all" devices in wmifs
 122                 * Added "lo" support only if aked via -i
 123                 * Added on-line time detection (using /var/run/ppp0.pid)
 124                 * Added time-out for the orange led. (one minute)
 125         15/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 126                 * Another wmppp-master.xpm.
 127                         Line speed detection being the main problem here.. :(
 128                 * Moved START_COMMAND / STOP_COMMAND to ~/.wmppprc
 129                         Return 0, everything went ok.
 130                         Return 10, the command did not work.
 131                         Please note, these functions are ran in the background.
 132                 * Removed the ability to configure
 133                 * When "v" is clicked, an orange led will appear.
 134                   if the connect script fails (return value == 10)
 135                   it will become dark again. Else the on-line detection will
 136                   pick it up, and "green" it.
 137         14/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 138                 * Added "-timer"
 139                 * Added "-display" support
 140                 * Changed pixmap to a no-name pixmap.
 141                         + Changed LED positions
 142                         + Changed Timer position
 143                         + Changed Stats Size
 144         05/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 145                 * Added ~/.wmifsrc support.
 146                 * Put some code in DrawStats
 147                 * Check devices when pressing "device change"
 148         03/04/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 149                 * Added code for wmifs
 150         28/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 151                 * forgot what i did.. :)
 152         27/03/1998 (Martijn Pieterse, pieterse@xs4all.nl)
 153                 * Added on-line detection
 154                         Scan through /proc/net/route and check everye line
 155                         for "ppp".
 156                 * A bit of code clean-up.
