Doestheserialhardwarehavebuilt-insupport
forprotocolssuchasSDLCandModBus?
BecausetheserialhardwareusesUARTsforcommunication,protocols
suchasSDLCandModBusarenotsupportedinhardware.However,
theseprotocols(ortheirderivatives)canbesupportedbysoftware
applicationsthathandletheprotocoltranslation.
