This software is still in beta state and may contain bugs. Not every feature is tested. The experimental version, when it is available, may have some bug fixes and new features, but is not yet verified to be stable on the 486 server.

Features:

  • DHCP
  • TCP and UDP sockets
  • IP version 4 (IPv6 not currently supported)
  • ARP
  • Congestion control
  • TSR program
  • Completely interrupt-driven
  • Uses asynchronic transmits if the packet driver supports it


System requirements:

  • 8088 or better CPU
  • Ethernet networking adapter or a SLIP/PLIP packet driver
  • 35 kB of free drive space
  • Consumes ~40 kB of memory when resident in memory


How to use this with lEEt/OS:

1. Load a packet driver. The packet driver must use software interrupt 0x60.
2. Load this TCP/IP stack by running TCP.EXE.
3. Start lEEt/OS shell (MAIN.EXE).
4. Load the TCP/IP driver (DRIVERS\TCPIP.EXE) for lEEt/OS using the driver loader (TCPIP.APP).
5. Load the background service program (TCPSERV.APP).
6. Done! You should now be able to use the networking applications.

You can move the TCPIP.APP and TCPSERV.APP binaries to the STARTUP/ directory to automate the steps 4 and 5.

How to use this with DOS:

Do steps 1 and 2 from above. The TCP/IP stack is now usable to the DOS programs.
