Sample code Introduction

Open COM Port Device(COM1~COM4)

portinfo_t portinfo1 ={'0' , 9600 , '8',  '0' , '0' , '0' , '0' , '0' ,  '1' , 0 };
portinfo_t portinfo2 ={'0' , 9600 , '8',  '0' , '0' , '0' , '1' , '0' ,  '1' , 0 };
portinfo_t portinfo3 ={'0' , 9600 , '8',  '0' , '0' , '0' , '2' , '0' ,  '1' , 0 };
portinfo_t portinfo4 ={'0' , 9600 , '8',  '0' , '0' , '0' , '3' , '0' ,  '1' , 0 };
//Default tty:COM2

Send the UP line message to LCM Device

   char upline[C32]={0x1b,0x51,0x41}; //for LCM UP line command
   text = gtk_entry_get_text(GTK_ENTRY(entry));
   sprintf(upline+3,"%s\r", text);
   PortSend(fdcom, upline, C32); //Send the message to LCM

Clear the UP line message of LCM Device

   char upline[C32]={0x1b,0x51,0x41}; //for LCM UP line command
   const char *clear = "";
   sprintf(upline+3 , "%s\r" , clear);
   PortSend(fdcom, upline, C32);

Send the LOW line message to LCM Device

   char lowline[C32]={0x1b,0x51,0x42}; //for LCM LOW line command
   text = gtk_entry_get_text(GTK_ENTRY(entry));
   sprintf(lowline+3,"%s\r",text);
   PortSend(fdcom, lowline, C32); //Send the message to LOW Line

Clear the LOW line message of LCM Device

   char lowline[C32]={0x1b,0x51,0x42}; //for LCM LOW line command
   const char *clear = "";
   sprintf(lowline+3 , "%s\r" , clear);
   PortSend(fdcom, lowline, C32);
