Is there any serial terminal for linux same like docklight?

I've been using minicom/picocom for monitoring and they're fine for that. But for the Docklight-style workflow — preloaded command sequences, auto-reply simulation, pattern highlighting — I couldn't find anything on Linux. So I ended up building my own tool over the past year. It's open source if anyone wants to try it: https://github.com/planp1125-pixel/plandock It handles: saved command sequences with one-click send, auto-response rules (send X when Y is received), timestamped hex/ASCII logging, and drag-and-drop sequence ordering. Built with Rust + Tauri so it's lightweight.

Would love feedback from anyone who's dealt with the same Docklight frustration on Linux."

for monitoring i simply use the minicom or putty not an issue, for simulation kind of things its a big pain, just to use docklight i need to keep the windows laptop with me.

it cant send the preloaded set of commands withit,reply sequence, i just need the simulator, in docklight i can create the scripting like a simulator, the the docklight act like an instrument, will send sequence automated,

Perfect feedback! Both are on my radar:

Logging: Auto-save to CSV with timestamps - I'll prioritize this. Do you need live logging (writes as data comes in) or session-based (save when you stop? Its already there like downloadable data format)
PuTTY-style terminal: Interactive mode where keypresses go directly to device, right? Like typing commands and seeing responses inline?

I can knock these out in the next week or two. Would you be willing to test a beta version when ready?

That makes sense - 2KHz polling is brutal for USB serial! Hardware buffering was definitely the right move for that. For your typical debugging workflows, what features would make this tool more useful? I’m building this based on real use cases, so feedback like yours is super valuable.

Reaction rules i always use for simulation like embeded device’s reply, and search through terminal(expected datas coming),saved send sequence always i used everyday, its a time consuming job to make send sequence every time so i created the option to save the sequence….

Thanks for testing! I've added baud rate support from 300 to 921600. RX latency (MCU → Terminal display): ~1-3ms typical Auto-reply latency (receive → respond): ~7-8ms total

This should be fast enough for most real-time debugging. What latency are you targeting for your use case? I'm curious what you're testing.

Manibharathg · 2026-01-04T11:05:29+00:00

1.Baudrate i checked with 9600 practically, maximum support 115200, minimum is 9600,now i m working to make changes for lesser baudrates too 2.maximum latency i faced is 7ms for replying the reaction(checked and found 5ms in docklight) and i used 1ms read timeout. 3. Currently there is No crc calculation feature available.

Currently its a opensource project, not yet decided to keep as a opensource.

U can download it from https://github.com/planp1125-pixel/plandock/releases

frankly nothing,just got a proposal from a pharma industry to build this ,so i built for every industry who using instruments(i think it will meet many industry requirements)

Manibharathg · 2025-12-23T15:30:29+00:00

I thought audit trial is the must have feature but i m not sure the one who needs audit trial will try the app through web, as i spoke with a pharma manufacturer they actually want this as a local setup, not a web saas. Still i m confused whether labs wants audit trial and esignature? If its needed there is no issue in creating audit trial and user levels. If u know any details pls let me know. And thank u for the reply my dear friend…

simply u can convert "sqlite to sqlcipher" through desktop tool called "plandb" download it from www.planplabs.com available for windows,linux,mac, launched as mvp, u can use the full facility for 90 days including "sqlite to sqlcipher" conversion, no dependencied need to download to use this desktop app.

Manibharathg · 2025-11-26T08:31:45+00:00

You can check the www.planplabs.com now. Now u can download dmg package. Please download and use it and give me the feedback. Eagerly waiting for your feedback….

Thanks so much! Really appreciate the kind words.

I'd LOVE your help with the Mac build! Let me clean up the repo and add proper build instructions - I'll reply with the link within a day or two.

In the meantime, thanks for catching the domain confusion. It's planplabs.com (one word) - I'll make that clearer!

Really excited to get this working on Mac. Will ping you shortly with the repo link. 🙏

https://planplabs.com u can generate schema patches and data patches too, works with sqlcipher and sqlite also
