CCS/TM4C123FH6PM: TivaWare_C_Series-2.1.4.178 USB library error

Part Number: TM4C123FH6PM

Tool/software: Code Composer Studio

Good day!

Recently I realized that USB library has small error:

//*****************************************************************************
//
// USB_CDC_SET_CONTROL_LINE_STATE, wValue
//
//*****************************************************************************
#define USB_CDC_DEACTIVATE_CARRIER                                            \
                                0x00
#define USB_CDC_ACTIVATE_CARRIER                                              \
                                0x02
#define USB_CDC_DTE_NOT_PRESENT 0x00
#define USB_CDC_DTE_PRESENT     0x01

But, in fact, as I open CDC port with terminal, code 3 (which maybe mean USB_CDC_DTE_PRESENT?) comes, and upon terminal shutdown code 2 (or 0, with different terminal) comes.
