When talking to a remote device over a serial port, what you are
receiving is fundamentally a byte stream, so the best way to handle it
is to admit that in your code. Read it into an array of (unsigned)
char, do any formatting / alignment checks that you can, and then
extract the data into the variables you want it in. If there are raw
binary values of more than one byte, extract them explicitly:

   MyWordVal = buf[2] + ( buf[3] * 256 );  /* data stream is little endian */

This is portable and clear to any future maintainer. The efficiency
loss is negligible.
