[SOLVED] Cpsc 3600-001 homeworks 1 to 5 solution

Developing a C program to support half-duplex layered communication. You are provided with the interface protocols (C function prototypes) for all the layers.  You need to implement these layers, including the development of peer-to-peer protocols.  You are responsible for implementing the C functions in layers 2,3, 4 and 5 (described below).  You do not need to implement layer 1 code – I’ve included a sample layer 1 code along with a sample main program.  When testing your submission we will use our own layer 1 that may be very different from the one included here – make sure your code does not depend on any specific layer 1 implementation!

Sample code for l1 is in the fold
