Function ReadCom8000nBytes

Description Reads n bytes from specific COM port of  multi-serial module.
This function is used for C/C++ compiler.

Function Prototype int ReadCom8000nBytes(int slot, int port, char *buf, int maxnum)
Return bytes read from buffer (0 ~ maxnum)
slot 0 ~ 3 for 4 slot
0 ~ 7 for 8 slot
port 0, 1         ==> I-8112 and I-8142
0, 1, 2, 3 ==> I-8114 and I-8144
*buf pointer to indicate the buffer that used to store input data
maxnum maximum size of bytes that want read from input buffer

 

Example
Function Num = ReadCom8000nBytes(0,1,Buf,100);
Return 100 (bytes)
Description Reads 100 bytes from COM1 of multi-serial module that plugged on slot 0 of I-8000 MCU.
