USB Serial Device (usb_dev_serial)

+//! +//! This example application turns the evaluation kit into a virtual serial +//! port when connected to the USB host system. The application supports the +//! USB Communication Device Class, Abstract Control Model to redirect UART0 +//! traffic to and from the USB host system. +//! +//! Assuming you installed TivaWare in the default directory, a +//! driver information (INF) file for use with Windows XP, Windows Vista and +//! Windows7 can be found in C:/ti/TivaWare_C_Series-x.x/windows_drivers. +//! For Windows 2000, the required INF file is in +//!

It reports DSR, DCD +// and CTS as high to ensure that the USB host recognizes that data can be +// sent and merely ignores the host's requested DTR and RTS states.
