Module spectrusty::peripherals::serial

Serial port related API and emulation of ZX Spectrum's peripheral devices using serial communication.

The terminology regarding serial port pins/lines being used in ZX Spectrum's technical documentation:

• RxD (Receive Data) Transmitted data from Spectrum to the remote device.
• CTS (Clear to Send) Tells remote station that Spectrum wishes to send data.
• TxD (Transmit Data) Received data from the remote device.
• DTR (Data Terminal Ready) Tells Spectrum that the remote station wishes to send data.

Structs

KeypadKeys	Every key's state is encoded as a single bit on this 20-bit flag type.
NullSerialPort	A serial port device that does nothing and provides a constant ControlState::Inactive signal on the DTR line and a DataState::Mark signal on the TxD line.
Rs232Io	The RS-232 serial port remote device.
SerialKeypad	The ZX Spectrum 128 extension keypad.

Enums

ControlState	A type representing a state on one of the CONTROL lines: CTS or DTR.
DataState	A type representing a state on one of the DATA lines: RxD or TxD.

Constants

BAUD_RATES	Spectrum's BAUD RATES.
DEFAULT_BAUD_RATE	A default BAUD RATE used by Spectrum.

Traits

SerialPortDevice

An interface for emulating communication between a ZX Spectrum's hardware port and remote devices.
