Definition in file usb_protocol_cdc.h.
Macro Definition Documentation
◆ CDC_CTRL_SIGNAL_ACTIVATE_CARRIER
| #define CDC_CTRL_SIGNAL_ACTIVATE_CARRIER (1 << 1) |
Carrier control for half duplex modems. This signal corresponds to V.24 signal 105 and RS-232 signal RTS. The device ignores the value of this bit when operating in full duplex mode.
Definition at line 262 of file usb_protocol_cdc.h.
◆ CDC_CTRL_SIGNAL_DTE_PRESENT
| #define CDC_CTRL_SIGNAL_DTE_PRESENT (1 << 0) |
Indicates to DCE if DTE is present or not. This signal corresponds to V.24 signal 108/2 and RS-232 signal DTR.
Definition at line 265 of file usb_protocol_cdc.h.
