This request allows the host to specify typical asynchronous line-character formatting properties, which may be required by some applications. This request applies to asynchronous byte stream data class interfaces and endpoints; it also applies to data transfers both from the host to the device and from the device to the host.

Control Signal Bitmap Values for SetControlLineState
　

Bit position	Description
D15...D2	RESERVED (Reset to zero)・・・・・・・・・・・・・・・・・
D1	Carrier control for half duplex modems. This signal corresponds to V.24 signal 105 and RS-232 signal RTS. ・・・・・・・・・・0 - Deactivate carrier ・・・・・・・・・・1 - Activate carrier The device ignores the value of this bit when operating in full duplex mode.
D0	Indicates to DCE if DTE is present or not. This signal corresponds to V.24 signal 108/2 and RS-232 signal DTR. ・・・・・・・・・・0 - Not Present ・・・・・・・・・・1 - Present
