 * MODULE: MISCLIB
 *
 * ROUTINES: netmain_init(), prep_modules(), station_state(), 
 * ROUTINES: station_state(), sysuptime()
 *
 * The functions in this file are generic functions

 *
 * PORTABLE: yes
 * They are portable for all targets that InterNiche supports. In future
 * if there is need for any of them  to be made target-specific, then
 * #ifndef wrappers can be provided over here.
