Under WSL1, the serial port COMX of the host can be accessed through /dev/ttySX. For example access COM11 via /dev/ttyS11. This mechanism works fine in esptool.py of esp-idf, but espmonitor can't work.

Can you try again, and pass -f to strace? I think the strace output you posted shows only cargo before it forks, so it doesn't contain the call that failed.

It seems to be the problem caused by WSL1 not supporting TIOCEXCL. Both esptool.py and minicom will not use TIOCEXCL, so they can work normally under WSL1. Is it necessary to use TIOCEXCL for rust's serial library? If it can be skipped, espmonitor and espflash will work under WSL1.

I believe the serial crate is just doing whatever it's doing; I don't have control over that. Maybe file a bug over with them?

It should really be an issue to serial. rust is very new to me, can you tell me the github repo URL of serial? Thanks

Sure thing, I believe it's https://github.com/dcuddeback/serial-rs

Feel free to leave this issue open for others to find, and so we can remember to follow up if/when things get fixed in the serial library.

Thanks, I have submitted dcuddeback/serial-rs#68 to serial-rs.
if you don't think it is necessary to keep this issue, I will close it.

Probably better to leave it open.
