KA9Q

What is KA9Q?

"KA9Q" is Phil Karn's ham radio call sign. Phil wrote a network operating system that implemented TCP/IP (from scratch) over amateur packet radio. We are not sure why he did this, but he sure did a good job. Phil calls sometimes calls his operating system, "NOS", but most other people call it KA9Q.

KA9Q runs in a DOS environment and uses just about any network adapter that supports a packet driver interface. Here are some places to go to learn more about it:
