Thanks.I see the display in HyperTerm at 16MHz.

Look like you have got the wrong baud rete, please make sure your setting that is correct in he Hyper-Terminal setting.
As my example code, I am usig 19200, N , 8, 1 with none-handshake, and the PIC18F458 is runing at 16MHz.

I use HyperTerm,but why does the display look like "奜O**B000000000022d" ?I just send "jdiwjewieujwoek" to com port.

This is very simple, use the Google search engine with the key word "VT-100", you will find a lots of specification for the VT-100.

Thanks,Ryang.I've received the example code.Can you show me some more detailed materials about VT-100?

I have send the CAN example code to you, that code is a temperature monitoring using VT-100 terminal. The applicatio code is under Microchip's PICDEM 2 Ples demo board with a PIC18F458 + MCP2551 (CAN transceiver).

VT-100 protocol are 19200, N , 8, 1 stop without handshake.

Thanks,Ryang.My Email is jamson_liu@163.com.Please send me the example,OK?

This function copies a given message to one of the empty transmit buffers and marks it as ready to be transmitted.
and the prototype definition show as below:

typedef unsigned char BYTE;

void CANSendMessage(unsigned long id, BYTE * Data, BYTE DataLen, enum CAN_TX_MSG_FLAGS MsgFlags);

Example code:

TX_ID1 = CAN_Slave_ID | 0b1010 ; // Setting CAN ID
TX_Data_Buf1[0]=AD_Buffer; // DATA0 = A/D Result
TX_Data_Len1 = 1 ; // 1 byte data to be send
CANSendMessage( TX_ID1,TX_Data_Buf1,TX_Data_Len1,
CAN_TX_PRIORITY_0 &
CAN_TX_STD_FRAME &
CAN_TX_NO_RTR_FRAME ) ;

The Function CANSendMessage( ) doesn't return any values back, I don't know what are you mean the return FALSE ?
I have a CAN example application C code that used the AN738 library and device also use the PIC18F458. I can send to you for reference if you interest it

Is somebody used the workshop ex738?Why the function CANSendMessage() return FALSE.My mcu is PIC18F458,and the compiler is HI-TECH PICC18.
