Introduction

Format Void SB_SendSerial (int handle, char *data, int length);
Parameter handle Handle to serial port or socket
data Pointer to the data to be sent
length Length of the data to be sent
Returns None
Notice When the transmit buffer is full, this function will retry up to 10 time in
20 msec period; it will return after transmission is completed.
SB_ReadSerial
Function Reads data from the serial port.
Format int SB_ReadSerial (int handle, char *data, int length, int wait_msec);
Parameter handle Handle to serial port.
data Buffer pointer where the read data will be saved.
length Size(length) of the buffer memory
wait_msec Time the function will wait for next received data after
reading from read buffer.
Returns 0 ~ n Size of the read data
Notice When wait_msec is set to 0 this function will only read data from serial
receive buffer; when set larger than 0, it will read data from serial
receive buffer, wait for time specified in msec unit, and then continue
reading data from serial port as one packet.
The maximum size of the data is same as buffer’s size, i.e. length.
You can use value obtained from SB_GetDelaySerial function or value
manually calculated for wait_msec.
SB_GetMsr
Function Reads MSR register value from serial port
Format Char SB_GetMsr (int handle);
Parameter handle Handle to serial port.
Returns
