Serial Port Driver

Document the Serial Port Driver concept in the wiki.

Value: 4

Concept Summary

Driver for serial ports (COM1-4) with UART register access. Handles communication via RS-232 serial interface.

Key Files

• core/src/driver/org/jnode/driver/serial/SerialPortDriver.java
• core/src/driver/org/jnode/driver/serial/SerialPortAPI.java

Occurrences

~100 references in serial package

Wiki Status

NOT documented

Bridges

Driver framework, Device discovery, Console

Instructions

Skill to Use

Use the update-wiki skill (load with: skill({ name: "update-wiki" }))

Context Research

Search the serial driver package (core/src/driver/org/jnode/driver/serial/) to understand UART register access, baud rate configuration, and how the driver integrates with the device manager.

Update index.md

• Pages table: Add entry if creating new page
• Concepts → Pages table: Add "Serial Port Driver" concept mapping
• Source Path → Pages table: Add mapping core/src/driver/org/jnode/driver/serial/
• Task Routing table: Add relevant task routes if appropriate

Requirements by Value

• Value 4: Update ALL 4 index sections + encourage 1-3 task routing ideas
• Value 4, 3: Update [[Glossary]] with concept definition
• Search broadly to capture context
