I also have my own minicom etc. alike tool in early phases but do not yet want to advertise it too much:
https://github.com/jarkkojs/tiorThe whole point starting to do this was to have a serial tool with great zmodem feature. Since a suitable crate did not exist I had to halt that and start working on this one.
Of course also for this pull requests are welcome. And I can promise to commit maintaining for some time as these are tools that I've needed in my work pretty much my whole career.
For text editors and email there's been always a great tool existing like vim and mutt for instance. For serial port, it was a downgrade to move on from MS-DOS to Linux, as minicom does not really compare to telex or telemate. And to this day there's nothing nearly as good as there were even for good old DOS.
