You're aware that SLIP has _no way_ to distinguish multiple L3 protocols?
Worse, as it has also no way to distinguish Van Jacobson - compressed TCP
from normal IP, so the first byte is used to do this decoding - with the
result that I doubt that the IP version half-byte is transmitted
I might be wrong, so feel free to read specifications and find out yourself;
just wanted to point you to a potential source of problem.
