Use the “port” variable to switch from COM4 to COM2, simply change
port=4 to port=2 .
If the program is set to use COM4, the code can be altered as follows:
4.6.1 To print from the COM port
The I-7188XA(D) library also supports functions such as printf() from
the standard C library to produce a formatted output.
The
printCom() function can be used for all COM Ports, and
printCom1/2/3/4 can be sued for individual ports. Before using the
printCom() function, the InstallCom() function must first be called. The
code is shown below:
if(data==’q’) quit=1; /*if ‘q’ is received, exit the program*/
}
}
RestoreCom(port); /*uninstall the COM driver*/
int quit=0, data;
InitLib(); /* Initiate the 7188xa library */
InstallCom4(115200L, 8, 0, 1); /*install the COM4 driver*/
while(!quit){
if(IsCom4()){ /*check if any data is in the COM4 input buffer*/
data=ReadCom4(); /*read data from COM4*/
ToCom4(data); /*send data via COM4*/
if(data==’q’) quit=1; /*if ‘q’ is received, exit the program*/
}
}
RestoreCom1(); /*uninstall the COM driver*/
