  According to a Siemens Application note from 8.3.94 this is too slow to
  meet GSM recommendations.  I hope it is fast enough for pratical purposes
  The alternative goes:
  CCPAR0 &= ~(CCTXMD|CCENA);
  waitloop 60Secs
  CCPAR0 |= CCRXMD|CCENA;
  I can't see any other possibility than a wait loop for the necessary delay.
