Based on some of the things Toby has said about LAP-M packet assembling
I'm led to believe that LAP-M packets have a header, a _variable_ length
data area, and then a frame end marker/crc.

What I'd like to know is how the data stream can be formatted so that
the header doesn't need to contain the length of the subsequent data but
that the receiving modem can somehow determine the length of the data
portion of the frame.

The only practical solution I can think of is to escape certain
characters when they occur in the data portion of the frame but if this
is the case then there must be some characters which take more bandwidth
than others.  What are these characters (if they exist)?

Mike
