Isn't it going to be hard to experiment with this code if you don't
even have the facilities available to compile it?  I must say, I've
looked on with amusement at the requests for compiled versions.  What
would you intend to do with it?  Won't it be difficult to interface to
whatever hardware you have?

Since the TNC incorporates the signal processing function (modem,
etc.)  as well as generating and checking the FCS of the HDLC frame,
how can you use this without changing the code in the TNC?  Wouldn't
it be easier to modify the KISS TNC code than hacking circuit traces?

If you constrain your choice of tools at the outset, you're
handicapping yourself unnecessarily.
