Used to run IP over AX.25 using KA9Q JNOS back in the day. HF at 300 baud simplex / half-duplex and VHF 144 Mhz at 1200 with similar characteristics. I bought some 9600 baud gear at one point but never got it all put together before moving on to the regular internet and (somewhat unfortunately) not really looking back. I remember transferring some uuencoded gifs via smtp... a couple of days later, if you were lucky, it would complete. I learned about how protocols communicate watching packet traces in KA9Q JNOS when I was about 14 years old. It was really easy when there were guaranteed to be multiple seconds between packets. I remember being 14 and feeling pretty suave when I figured out how to telnet into an SMTP server to send mail... of course that is old hat but still good common troubleshooting these days!
