SHIP:Port:USBF CDC

USBF (i.e. USB Device) Communications Class Device (CDC) port variables are used to configure the way a SIM communicates with some other device and are referred to in the format "platform.USBF_CDC0", "platform.USBF_CDC1", etc.

USBF_CDC devices act just like UARTs, and have a subset of the UART portvars.

Multiple USB Device protocols (aka "classes") can be active on the same port simultaneously. For example, on USB device port 0 on a platform, you can have:

• USBF_CDC0, implementing the Communications Device Class (aka "serial port over USB"), and,
• USBF_VENDOR0, the Vendor (or "Raw") class bound to a SHIPBridge Protocol link exchanging data with another board

both operating simultaneously.

If you attempt to set an invalid value for any of these portvars, the value of the portvar will not be changed. (see UART_FLAGS)

Portvar	Data Type	Permissions	Description
rate†	Integer	Read/Write	The baud rate.
bits†	UART_FLAG	Read/Write	The number of bits per character set.
stop†	UART_FLAG	Read/Write	The number of stop bits sent after each character set.
parity†	UART_FLAG	Read/Write	The parity bit sent after each character set.
