NutIP, a web server and TCP/IP stack for HP-41 Message #1 Posted by Khanh-Dang Nguyen Thu-Lam on 22 Aug 2009, 7:40 a.m. Hi all, NutIP is a ROM for HP-41 (C/CV/CX). It implements a full-featured TCP/IP stack and a web server. I never ran the code on real hardware because devices are rare and expensive (one need a HP-41, a HP-IL module, any hardware that let you burn a ROM, a HP-IL/RS232 transceiver...). Though, I managed to run NutIP on emulators. It works well with nonpareil and Emu41. You can download source code (under a BSD-like license), binaries and documentation at http://perso.orange.fr/kdntl/hp41/. Hope you enjoy it, Khanh-Dang

Re: NutIP, a web server and TCP/IP stack for HP-41 Message #4 Posted by Egan Ford on 22 Aug 2009, 2:24 p.m., in response to message #3 by hecube I have all the necessary gear, just no time right now. I'll give it a shot next month. I expect the only issue will be with the HP-IL/RS232. It will need some unknown setup. If (big big IF) I can get it working perhaps I can host a section of the HHC2009 website. :-)

Re: NutIP, a web server and TCP/IP stack for HP-41 Message #8 Posted by Christoph Klug on 24 Aug 2009, 2:57 a.m., in response to message #7 by PeterP Dear Peter, some knowledge about HP-41 and RS232 you find in the IL2000 manual(transfer between two HP-41, and transfer between HP-41 and EMU41) and on the HPCC webpage under HP-41 calculator... Regards - Christoph

Re: NutIP, a web server and TCP/IP stack for HP-41 Message #9 Posted by Khanh-Dang Nguyen Thu-Lam on 24 Aug 2009, 4:16 a.m., in response to message #7 by PeterP If you are using a HP-82164A peripheral (HP-IL/RS232 transceiver), you should use 9600 8N1 (default settings). You may want to read the documentation for more details.
