• DSZ zmodem and Mystic

    From Cozmo@21:3/135 to All on Sat Jul 1 00:05:01 2023
    Anyone here ever use DSZ zmodem? Having a problem with it d/l ing .zip files. I have a door that will let you view and d/l text files. You have the option of d/ling the file with or without zipping it. Files d/l fine in .txt format but when it gets zipped and try to d/l it i get errors and it doesnt complete the d/l . The same .zip file will d/l fine if i add it to the Files section in Mystic.

    Any ideas?

    what sorts of errors?

    if you have to use an external zmodem maybe try out pdzm (public domain zmodem) or something. (https://pcmicro.com/netfoss/download.html)

    if it's calling dsz.exe directly with no way to set parameters, maybe we can put together a simple dos shim program to translate them

    Could it be fossil related?

    If you connect to your BBS using a "raw" protocol, not "telnet protocol" (I think syncterm can do raw), does it work?

    Getting a ton of CRC32 Errors

    I using Telnet to login. I have used PD Zmodem and I get the same results.

    I'm using a .bat file that the Door uses to download the file. And have tried many different parameters without any luck.

    I have to run the Door in DOSBOX. Using win7 32 bit. Not loading NETFOSS or any fossil.

    I just connected using "RAW" and it worked flawlessly! What's up with that?
    So telnet is getting in the way? I was hoping it would work using telnet mainly because most people seem to use that to connect.

    telnet isn't 100% transparent like a "raw" connection. it has a handshake protocol to determine things like whether to echo keyboard input back, a way to report when the terminal window is resized, features to do stuff "out of bounds" like kill the currently running program, etc.

    it's likely the zmodem transfer is filled with what the client thinks are telnet commands.

    So since this door does downloads, its not (and probably would know anyway), putting the telnet session into raw mode. So binary transfers that speak that have telnet codes will be intercepted and not passed down to the downloading program.

    Yeah, this is all a bit above my tech level :( but I do understand somewhat.

    Thanks for the input!

    Well I can at least download the .txt files just not .zip files. A bit dissapointing but hey we tried. :)

    If I were to guess, it's that there's a disconnect with the telnet control character with DSZ inside the door. ascii 255 is a control character that must be doubled if it's a telnet connection from the outside. The .txt probably doesn't have this and the .zip probably does. Is the door using its' own DSZ, or a separate exe? If it's separate, you might be able to swap a param for this.

    Yeah, it just needs to double up ascii 255 characters when sending to the client. (and deal with them in receiving). Not sure if there's an option for that with the dsz client the door is using.

    The Door is using a seperate .exe (DSZ.EXE) I don't see any parameters to that would do what you are describing.

    thats probably correct. i had this with sexyz under mystic. fixed it bybusing the -telnet argument after Digital Man kindly pointed that out.

    use sexyz and it will work for you. binaries of 2.o are available at xqtrs bbs, or at mine i think.
