To some extent this will epend on your OS and machine architecture.

Assuming the data arrives in sensible line format then you might 
be best ton read the line into a buffer and then use slicing to 
access the data within it. If the data does not naturally arrive 
as a line then you may need to use the fctl or ioctl functions 
to read from the serial file decriptor the required number of 
bytes as they arrive in the buffer.
