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.

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.

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