  Hi!      sory for my bad english :)
  I have asked before help for this and thx for replies.
  Now I found some  piece of code so I have a program that I want but I can't understanding how exactly working that thing.
  Here are the Codes:
  
  #include <conio.h>
  #include <stdio.h>
  #include <stdlib.h>
  #include <dos.h>
  #define PORT1 0x2F8
  
  void main () {
      clrscr();  
      int c, ch;   
  
      outportb(PORT1 + 3, 0X80);                  //NO IDEA
      outportb(PORT1, 0X0C);                       // I think thisone for speed of connection as 9600bps or something like that I m not sure.
      outportb(PORT1 + 1, 0X00);                  //NO IDEA
      outportb(PORT1 + 3, 0X03);                  //NO IDEA
      do {                                         
          c = inport(PORT1 + 5);
          if (c&1)
          {
              ch = inport(PORT1);
              printf("%c", ch);
          }
          if(kbhit())
          {
              c = getch();
              outportb(PORT1, c);
          }
          if (inportb(0X3FD & 3)) {
              printf("Error!");
              getche();
          }
          if (!(inportb(0x3FE) & 20)) {
              printf("Cable unpluged!!!");
              getche();
              break;
              }
      }while(c!=27);
  }

   

  now  here is my problem:  I need a program with these attributes

  57600    bps                  
  0           control for singleness             // can someone explain what is that control ? it is for (dual) for (single) or (no control)
  7           bit data  (which is I ll send to the other computer)
  1           stop bit
  
  If someone can tell me how to use that 4 definations or anywhere to find any informations about them I ll be realy grateful. thx for replies
