Align serial inter-frame/inter-character timing with the Modbus spec by correcting microsecond calculations and using a 750µs char timeout above 19200 baud. Refactor SerialParameters constructors to centralize defaults, enforce baud rate > 0, and add tests for bit-per-character/stop-bit calculations plus invalid baud rate rejection.
Adjust serial timing to honor the Modbus RTU 3.5 character inter-frame gap more accurately.

Refactor
SerialParametersconstructors to centralize defaults, enforce baud rate > 0, and add tests for bit-per-character/stop-bit calculations plus invalid baud rate rejection.Changed the default inter-message gap from 4 to 3.5 characters to match the Modbus specification.
