• path -string
• Returns:Promise<CP2102N>

Open an interface withpath (i.e./dev/cu.usbserialXXX on macOS,/dev/ttyUSBX on Linux). Throws ifpath is not a valid CP2102N device.

• state -{ [pin: number]: boolean }
• Returns:Promise<{ [pin: number]: boolean }>

Set state of pins to high (true) or low (false). Returns the latest state.

• Returns:Promise<{ [pin: number]: boolean }>

Get state of all PINs.

• state -number
• mask -number
• Returns:Promise<number>

Set state of masked pins in bits. Returns the latest state bits.

• Returns:Promise<number>
