Minimalistic TUI serial monitor.
```
cargo install smon
```
Run with no arguments. smon enumerates available serial ports, lets you pick one with an fzf-style filter (type to filter, arrow keys to move, Enter to select), then prompts for a baud rate. Once connected, it works like a shell: keystrokes go to the device, incoming bytes scroll in the pane.
```
smon
```
Press `Ctrl+]` to quit.
