I have written a TCP/IP from scratch in C for MS-DOS which I and many
others are now running. Besides fullblown TCP and IP/ICMP, it contains
SLIP, ARP, Ethernet and AX.25 (amateur packet radio) link drivers, UDP, and
clients and servers for SMTP, FTP and Telnet. At present routing tables
are manually controlled, and there is no domain support (you need to specify
IP addresses).
Since I was more interested in writing protocol code than in reinventing
another toy operating system, I structured the code as a big commutator
loop with extensive use of upcalls. I was pleasantly surprised to see
how far I got with this approach, but I was also hoping that something
just like MINIX might come along. However I'm in a holding pattern until
I am able to get the MINIX source.
I did this work specifically for amateur packet radio, but I'm willing
to kick it out into the MINIX community for noncommercial use. Copies
of the current MS-DOS version can be found on louie.udel.edu (10.0.0.96)
as /pub/net*.cpio.Z.

It has drivers for the 3-Com Ethernet/802.3 controller, a HDLC-PAD called the PC-100, and SLIP. It is copywrited and available for cost of media ($5.00) in source form with binaries for the IBM-PC under DOS.

UUCP is nice, but... There was recently an item posted in net.ham-radio.packet regarding a TCP implementation for use in packet radio. It is available by anonymous FTP from louie.udel.edu as /pub/net*Z (compressed ASCII cpio archives). This might make a good starting point for such work.

I haven't worked for Bell Labs since December 31, 1983 (over 3 years ago). 2. I wrote this package on my own time, at home, on my own PC. I did this specifically so I would be free to give it to the amateur packet radio community; for this reason I would feel better if people did not mention my employer in connection with this project. Noncommercial, educational and/or individual use (i.e., the kinds of things MINIX is also intended for) is fine by me, even if you're not a ham; as John says, the only thing I object to is somebody making money off my efforts. I am most interested in porting my code to MINIX, and if someone volunteers to help, it'll get done that much faster. A MINIX system running my TCP/IP would be an ideal server node on the amateur radio network. Phil

When the IBM AT BIOS does a disk read or write, it first outputs a command to the command port of the disk controller. It always waits for this action (giving the command) to complete. However, when it actually starts the read/write operation, it makes a call to a routine called WAIT (page 5-111) of IBM AT Tech Ref, and that routine does a INT 15H to signal it's gone into a wait loop. At this point, save the state of the machine, and dispatch another task. Then, when the disk operation completes, it will issue another INT 15H (with a different code in AX). Simply (ha ha!) restore the state of the machine and go back to where you where in BIOS. Be aware, however, that you need a real operating system on top of this that can serialize disk requests because, though some things like BIOS provide a little bit of re-entrancy with the POSt-and-WAIT operations, the usual PC disk controllers are NOT "re-entrant" (i.e. only one I/O channel).

But don't let us stop you if you are ready and eager to take on then task yourself! Phil
