Enumeration 

Description 

VM_DCL_SIO_COMMAND 

Commands for serial port hardware. DCB stands for Device Control Block. Call vm_dcl_control with VM_DCL_SIO_COMMAND_SET_DCB_CONFIG to config uart driver. 

VM_DCL_SIO_DEVICE_SERIAL_PORT 

Device identifiers for serial ports. Pass this to vm_dcl_open to select one of the serial port devices to use. Currently, only the hardware UART port (TX/RX pins) is available on 2502A. The USB COM ports are used by SDK for debugging and SDK functions, therefore not available to the application. 

VM_DCL_SIO_EVENT 

VM_DCL_SIO_EVENT are serial port hardware events that can be registered with vm_dcl_registercallback. 

VM_DCL_SIO_UART_BAUDRATE 

VM_DCL_SIO_UART_BAUDRATE defines values for the baud_rate field in the serial port configuration structure vm_dcl_sio_config_t. 

VM_DCL_SIO_UART_BITS_PER_CHAR_LENGTH 

Defines values for the data_bits_per_char_length field in vm_dcl_sio_config_t. This configures the length of data bits during UART transmission. 

VM_DCL_SIO_UART_FLOW_CONTROL_MODE 

Defines values for the flow_control field in vm_dcl_sio_config_t. This configures hardware or software flow control is used during UART transmission. 

VM_DCL_SIO_UART_PARITY 

Defines values for the parity field in vm_dcl_sio_config_t. This configures the behavior of parity bit during UART transmission. 

VM_DCL_SIO_UART_STOP_BITS 

Defines values for the stop_bits field in vm_dcl_sio_config_t. This configures the stop bits during UART transmission. 

VM_USB_CABLE_STATUS 

The USB cable status. 

Structure 

Description 

vm_dcl_sio_config_t 

This structure is part of the parameter structure vm_dcl_sio_control_dcb_t struct for command VM_DCL_SIO_COMMAND_SET_DCB_CONFIG. This structure allows developer to configure UART parameters such as baud rate and parity bits. Refer to vm_dcl_sio_config_t for usage example. 

vm_dcl_sio_control_dcb_t 

Parameter structure for command VM_DCL_SIO_COMMAND_SET_DCB_CONFIG, which configures the parameter for the serial port device.
