Detailed Description

Per-channel Stream adapter for one SC16IS752 UART.

This nested class exposes a standard Arduino Stream interface for a single UART channel and forwards all operations to its parent SC16IS752 instance. It allows sketches to use channelA() and channelB() like regular stream objects while still exposing selected channel-specific helpers such as begin(), linestate(), interruptPendingTest(), enableRs485(), and interruptControl().
