It seems to me like there are a lot of important things left undefined in that document: It constantly refers to ZDLE-encoding, but what is it? It doesn't define the CRC polynomial it uses. Nevermind, I found it through trial and error. The CRC16 poly is 0x I initiate the transfer from the server with the following command: sx --zmodem helloworld. B 30 30 0D 8A 11 Three issues with this: Are the padding bytes 0x2A arbitrary?
Why are there two here, but in other instances there's only one, and sometimes none? Bbe 35 30 0D 8A Solved; it follows whichever mode you're using. Immediately after this frame, the server also sends the file's metadata: 68 65 6C 6C 6F 77 6F 72 6C 64 2E 74 78 74 00 31 helloworld. Ba8 37 63 0D 8A 7c. The server ends with these frames: 18 68 05 DE 02 18 D0. Improve this question. Jeff Jeff 7, 3 3 gold badges 21 21 silver badges 31 31 bronze badges. I am working on precisely the same thing for precisely the same reason; If you ever made this work, and have source code, that would be awesome How did this end up?
After spending a few days coding to get reliable zmodem receive working, I gave up and just shelled out to lrz. Worked in a day. It's nowhere near as clean but I didn't really feel like spending more time on a venerable but obsolete protocol Also, beware!
I found a few other zmodem code libraries out there but they were all totally unreliable! The client ends when done. The server runs endless until closed by the user or an application.
The software provides status information. All status information and printouts can be routed into a log file informational mode or disabled quiet mode. A low level data trace function is offered as well. What commands and options does it offer? The ZMCS software is driven by command line parameters:. A complete description of functions and parameters and more samples can be found in the Manual. Do I have to develop anything or do I need a SuperCom software in order to execute it?
No, ZMCS is a ready to run application offering the described funtionality. You just copy it to the station you want to use it. Does it support binary files? Yes, ZMCS can transmit text files and binary files. Is it possible to run invisible in background? Yes, the ZMCS application can run completely hidden and in background without any visible window.
What security features does it offer? Files to be transmitted or retrieved must be located inside the working directory. Thus protecting other directories. In order to redirect the working directory just attach a directory name to this parameter e. Once set it expects from every client to authenticate itself by entering username and password. This mechanism also allows to specify a per user working directory, if required. What is this Job File? A Job File is similar to a script file. It contains commands to be executed while a client is connected.
Am I missing something? Any insights are greatly appreciated. Depending on how strict 'outside of Tera Term' is, you could try using a TeraTerm macro , which reads like a programming script and can be executed from the command line.
Macros have pretty reasonable capabilities; I've just made one which connects to a raspberry pi over TCP but would work with serial , logs in, prompts the user to select a file then sends said file over ZMODEM. Sign up to join this community.

When this command is executed, a file selection dialog box will pop up. After selecting the file to be uploaded, click OK to start the upload process. The speed of uploading depends on the condition of the network at that time. RZ: running this command will pop up a file selection window, where you can select files locally and upload them to the Linux server.
Select the file in the pop-up box.
