Hello group, I write this message to share a little news about what I was doing in my spare time these last two months: porting picoTCP to DOS.
picoTCP is a modern, dual-stack, open-source TCP/IP stack. It has been created by the good people at Intelligent Systems (Altran), primarily as a stack designed for embedded computing (hence hardware with very limited horse power). It is backed by a well established corporation and it's actively maintained. I played with the stack for some times now, and ended up building an entire DOS compatibility layer around it. A few patches were required to the stack, a few days of development, many hours of debugging - but here it is - the first public release of picoTCP for DOS! http://picotcp4dos.sourceforge.net The project contains three major parts: - ipcfg: a little tool that allows to configure networking on your DOS machine (IP, DNS, etc). No, it's not a text file - I wanted to avoid the complexity of parsing a text file, and opted for a binary configuration file that is manipulated via ipcfg. It's much more flexible that a text config file, while being much easier/faster to load at runtime. - ping: no need to explain, I guess... my ping tool for DOS, based on picoTCP - crucial when it comes to testing your networking - an OpenWatcom library package (openwatcom, large memory model) - this is for the fellow developers that would like to use the DOS version of picoTCP inside their network-enabled, 16-bit DOS programs. I integrated a packet driver schim, a DOS-compatible timer, as well as the whole IP configuration logic, so it is now a simple (2 functions!) public API that allows to load picoTCP, use it, and unload it. *** Short how-to *** 1. Download picotcp4dos and unzip it on your drive 2. Set the location where the config file will be stored, for example: SET PICOTCP=C:\PICOTCP.DAT 3. Bind picoTCP to the interrupt vector of your packet driver, example: ipcfg int 60 4. Configure your IP settings using ipcfg, or use DHCP (ipcfg dhcp) enjoy!
