PUTTY YMODEM FILE TRANSFER UPDATE
The options are added to update client/server working direction, and preset the rz files to avoid the file selection. Note right of server: start transmitting at the responsed length or 0. ack with the same length if ok, otherwise 0. Note left of client: verify the CRC32 of the file heading content in len length. Note right of server: calc the CRC32 of the existing the file content. Note left of client: start transmitting at the responsed length or 0.

Note left of client: calc the CRC32 of the existing the file content.Ĭlient->server: ZCOMMAND_CHECK_LEN(CRC32, len) When the cursor position is larger than 4 GB, the 64bit binary frame will be used while the rest is as it was.Ģ extra messages ZCOMMAND(ZCOMMAND_CHECK_LEN) and ZACK(pos) are involved. In order to achieve this feature, a 64bit binary frame with CRC32 is defined. The file cursor position in ZMODEM protocol message(ZRPOS/ZDATA/ZACK/ZEOF) is defined as 4 bytes, which limits the file size max to 4 GB. However, the empty directory is ignored at the moment. The server/client check the ‘/‘ character and make the directory. I just send the relative path of the file as its filename. The feature is already supported in the ZMODEM protocol. sz workflow sequenceDiagramĬlient->server: FIN rz workflow sequenceDiagram The original ZMODEM protocol is available via the link or the markdown version. I have implemented some more features and protocol extensions, which are detailed in the following chapter. For the other features in ZMODEM or YMODEM/XMODEM, will be gone with the wind if no one bring it back in the future. So it is a single thread.Īs it is a long time after the ZMODEM protocol was invented, rzsz-nd starts from a basic feature, which is sending/receiving plain file in ZMODEM, without any conversion and encryption. It is a utility tool, which means it must not occupy lots of resources from the other logical server. I have written build scripts in plain Makefile, so it is not autoconf. I have some tools on hand, the FSM and the multi-jobs Processor in C++. To get out of this dilemma, I decide to re-implement it again. And the worst thing is, this happened again and again. Sadly I gave up before I got drowned in the source code(Sorry to say that, it is my problem). Those thinking keep following me and someday I couldn’t stand for it and downloaded its source code. Then, why do I make another implementation of it? Well, as a user, I have a lot of thinking, like what if it can blablabla or why can’t it be blablabla. It is so convenient that after I implemented the ZMODEM feature in putty-nd, I seldom use other tools to transfer files. OverviewĪs well-known, lrzsz is a very handy tool to transfer files along with the existing terminal.
