Perhaps you can use regexp as a work around?

octave:81> str = "19:45:21.3366; 00:25:56:84:b2:55; 00:e6:4b:bd:ac; 15887; 
0x0028e36";
octave:82> pat = "[^;|^\\s]*[^;|^\\s]";
octave:83> regexp(str,"[^;|^\\s]*[^;|^\\s]","match")
ans =

{
  [1,1] = 19:45:21.3366
  [1,2] = 00:25:56:84:b2:55
  [1,3] = 00:e6:4b:bd:ac
  [1,4] = 15887
  [1,5] = 0x0028e36
}

The result is all character data, so you'll still have to convert the 4th field 
using str2num.
