Production data cut

[inlancersystem4]

serial data transmission works perfectly during development (tauri dev), but in the production (tauri build) version, the data write often stops midway or gets truncated.
The issue appears consistently — only partial data is sent, and communication halts until the app restarts.

Hi, try using setTimeout (JS) or set_timeout (Rust) before calling write.
From what I can see in the Rust serial port code, there’s a common timeout for both writing and reading:
