| Post subject: | TCP/IP source of information |
hello all, I am working on a project called engine simulator with a c64 and ext self made hardware (http://www.lemon64.com/forum/viewtopic. ... ght=engine). As you can read from the link above, I am going to test external hardware modules (with their dedicated sw) that communicated via hardwired signals (4-20mA I/O, digital I/O,.....) and also using TCP/IP. At the moment I have interfaced the C64 only to the hardwired signals, but I would like to add the capability to read the TCP/IP information send by these external modules. While I have pretty good experience with hardware and 6502 assembler, I have almost none with TCP/IP, and I don't know where to start. I am thinking about using an MMC-replay+RR-NET. Can anybody please point me to a good sorce of information about the TCP/IP (for beginners)? If interested I could post the schemes of my self made hardware that interfaces with the C64. regards, Ready. |

I don't think that any "TCP/IP for beginners" crap will help you out at all. I think you have to get bored with the RFCs. This is your source of knowledge: http://www.ietf.org/rfc.html Maybe you could start out with RFC 1180 which is sort of a tutorial for the whole stack. Then you would need to get down and dirty with:
RFC791 - IP RFC792 - ICMP RFC793 - TCP RFC826 - ARP RFC894 - IP over Ethernet. ..and maybe a few more depending on what you whish to achieve. But all these are only the protocols. You still need a driver and a stack implementation which supports those protocols. Other people here can surely point you in the direction of various stack implementations with support for the hardware you are planning to utilize, if you don't want to code the whole thing yourself. |

thanx Devia, I will read though the links you pointed. I don't mind coding stuff myself, I just would like to avoid re-coding other people have already coded. thanx, Ready. |

To get anything useful out of it you need a complete TCP/IP stack. But why reinventing the wheel! There are already a couple of working alternatives out there. You might wanna take a look at uIP for instance. Easy to use with the Contiki 2 framework even. |
