An RFCOMM frame

Fields

address: u8

Address byte (DLCI + C/R + EA)

control: u8

Control byte (frame type)

length: u16

Length of the information field

data: Vec<u8>

Information field (data payload)

fcs: u8

Frame Check Sequence

credits: Option<u8>

Credit byte (present in UIH frames when P/F bit set in credit-based flow)
