Does anybody out there know of a C64 term program that has Z-Modem file protocals? Can you tell me where I could possibly FTP it if so? Thanks. Chris Bray csb1@uafengr.uark.edu

Every couple of weeks someone asks that same question, and the answer remains unchanged: No, and don't hold your breath waiting for it. It's possible, but then again so is flying to Mars, but I don't see hoardes of people lining up at the ticket counter. -- UUCP: watmath!xenitec!zswamp!root | 602-66 Mooregate Crescent Internet: root@zswamp.fidonet.org | Kitchener, Ontario FidoNet: SYSOP, 1:221/171 | N2M 5E6 CANADA Data: (519) 742-8939 | (519) 741-9553 MC Hammer, n.

I agree, although Z modem would not provide much over all speed preformance then other protocols, however the other advantages of Z modem should justify its development for the commdore computers. As a telecommunications programmer, I have looked at the souce code of Zmodem on other CPU systems, and its looks quite complex. The biggest problem with it on a C64 would be lack of memory. PS - I have finaly found a very good soultion to the problem of downloading files from Unix bases systems to the C128. From FTP I can fire the files I want to my unix home directioy, but getting them from there to my C128 was the tuff one. Kermit on the 64 really sucks! Im sorry, but Kermit in general is a very crappy protocol. The solution: Xmodem 1K CRC. Works fast, and works good up to high baud rates. ctfm

YMODEM (the REAL YMODEM, the batch protocol, as opposed to the XMODEM-1K) solves 1 and 2 above. CRC-16, as implemented in all but the simplest XMODEM drivers, already provides an incredibly small chance of undetectable eror (in fact, I find it hard to believe that people would increase overhead measurably to cut the chance of undetected error almost immeasurably). 4 is a valid point, I concede. I also concede that it would be nice if we could all run a mile a minute. As one of the people who occasionally is told that I SHOULD give ZMODEM a shot, I reserve the right to go about hollering "It ain't worth it!" -- UUCP: watmath!xenitec!zswamp!root | 602-66 Mooregate Crescent Internet: root@zswamp.fidonet.org | Kitchener, Ontario FidoNet: SYSOP, 1:221/171 | N2M 5E6 CANADA Data: (519) 742-8939 | (519) 741-9553 MC Hammer, n.

Sounds good, but what terminal program do you use that supports this protocol? I've been trying to find a good C64 program that supports BATCH file transfers of W/X/Y/Zmodem. I have Multiterm 6.0, which claims to support batch Xmodem, but our Unix system doesn't believe that for a moment. ::sigh:: I realize that many 128 programs support these protocols, but I have yet to run across a C128 terminal program that doesn't assume that your 80 column monitor is working.

You need to use the ANSI 80 column mode with Novaterm, and set your terminal emulation on the *NIX machine to "an".

Well, the terminal Im using to make the transfers is called Cterm, but its not really a comerically aviable terminal program. Its a subplemnt overlay for the BBS software that I run. (Cnet 128 v4.0). Nova Term 9.1 fully supports Xmodem CRC 1K. However, its not a batch protocol. ctfm

Well, in that case I'll give up on NovaTerm. I was unable to get the program to even pretend that it worked at 2400 baud. Very disappointing.

Why is it that everyone who says that does so as if they expect someone else to do it? I have put in a lot of time on high speed serial drivers and CRC generators; I did so because I thought it worthwhile. I did not whine in public groups that SOMEONE ought to do it because it's probably justifiable. If YOU wish to do the ZMODEM port, then you have my most sincere best wishes - and any help that I can offer, short of doing it for you. >The solution: Xmodem 1K CRC.

This is preceisely what I've been telling ZMODEM fans; YMODEM isn't ZMODEM, but it's damned good anyways and several orders of magnitude simpler. -- UUCP: watmath!xenitec!zswamp!root | 602-66 Mooregate Crescent Internet: root@zswamp.fidonet.org | Kitchener, Ontario FidoNet: SYSOP, 1:221/171 | N2M 5E6 CANADA Data: (519) 742-8939 | (519) 741-9553 MC Hammer, n.

HEY!!! I was not crying! Im working pretty hard on my own protocol now for the commodore. Its acutally a networking protocol over modems, but I think I have to agree with you Mr Math....Zmodem is just to big, complex, and nasty to do on a 64. A 128 maybe! <GRIN> ctfm
