00004   This file exists as a work-around for the hardware dependant calls
00005   to slip_arch_init.
00006 
00007   Current the prototype for slip_arch_init is slip_arch_init(urb)
00008 
00009   and a typical call is something like
00010   slip_arch_init(BAUD2URB(115200))
00011 
00012   BAUD2UBR is hardware specific, however. Furthermore, for the sky
00013   platform it's typically defined with #include "dev/uart1.h" (see
00014   rpl-boarder-router/slip-bridge.c), a sky specific file. dev/uart1.h
00015   includes msp430.h which includes the sky contiki-conf.h which
00016   defines BAUD2UBR.
00017 
00018   To me, the correct think to pass is simply the baudrate and have the
00019   hardware specific conversion happen inside slip_arch_init. 
00020 
00021   Notably, most implementations just ignore the passed parameter
00022   anyway. (except AVR)
