Learned how async works in Rust and it looks like straight-forward to convert #zmodem2 crate to that as I have state machine alike structure for both send and return. Given how slow these transfers I make it async only, not async opt-in feature.
After that only some minor things need to be added and fixed and I can finally start gluing it to https://github.com/jarkkojs/tior and start working on its UI again.
For tior I’ll switch also switch to
serial2 crate, which provides simpler API, a pro-active maintainer and fully working Windows serial support, which is not the case with
With the asynchronous ZMODEM crate (right now the standard is invoking external program) it is possible to implement file transfer dialog, which shows progress, cancels the transfer according to the specification and generally not get a feeling that system is somehow halted :-)
