Re: JOYNET information and MISC
My protocol is delay insensitive. You can't make a delay insensitive protocol and use timeouts at the same time. You can, just set the timeout to, well, 3 minutes (255 interrupts). That will always be ok, because even the slowest MSX can transmit a byte in 3 seconds... Actually flipping both D0 and D1 (happens only as transmission error) is what causes the protocol to hang in the first place. I can ofcourse make my protocol partially delay insensitive. But there is another problem: performance. If I put a timeout counter in the inner loop, the speed will suffer a lot. So now I'm thinking about using the interrupt to generate timeouts. That's true, although if you put it on the interrupt it won't take that mucht time. ~Grauw MSX Mailinglist.

By the way, Maarten, can't you indicate to the opposite computer that an error occurred by BOTH flipping D0 and D1??? (That can be used as an indication to restart the handshake-process...) And if you combine that with some timeouts... You should be able to let it recover from errors. My protocol is delay insensitive.

Re: JOYNET information and MISC
information and MISC Hello everyone, Just have two questions: 1/ where to get the JOYNET BIOS and latest specifications for the cable? The latest specs for the cable are on my official JoyNet homepage at http://datax.cjb.net/ Protocols are still in development, however I will try to finish one; but in a few days (before saturday) I will add a section to the page with proposings for a 2-computer and a network-protocol. Which you still have to program, ofcourse. Also, solutions for the "interrupt-problem" will be given (the standard MSX interrupt resets the JoyNet pins). ~Grauw MSX Mailinglist.

Errors are rare, so for testing the protocol is OK, but there errors are just a bit too frequent (once in 80 megs if my memory is correct) to call this protocol reliable. Laurens also made a protocol, I don't know if his sources are avialable (either through WWW or my request). And there is the JoyDsk ROM, a diskROM-like program that enables you to use a PC like a disk drive through the JoyNet cable (DOS1 only at the moment). Bye, Maarten MSX Mailinglist.
