    _______________________________________________________

Details:

Function pppOverSerialOpen() uses function sys_msleep(..) , but function
sys_msleep() uses sys_sem_wait_timeout () that in turn  uses sys_timeout (). 
The bug consists in that the thread calling function pppOverSerialOpen with
linkStatusCB ==0 (callback not used), is not thread lwIP and does not contain
timeouts(changelog 2007-05-22 Frйdйric Bernon). It is true for functions
pppOverSerialOpen(), pppOverEthernetOpen(), pppClose().
