go-modemmanager

A Go wrapper around ModemManager's D-Bus API

🚨🚧 WIP/Experimental 🚧🚨

---

What this is

• Wrapper for ModemManager's D-Bus API in Go
• (Mostly) usable
• Not battle-tested
• Unpolished

Usage

$ go get -u github.com/parrotmac/go-modemmanager

Run Example

$ go run cmd/dump.go

On a system with two Modems, the (formatted & slightly tweaked) output might look like this:
