I think changing the <= to < fixes it here.

with ipaddress a string equal to "???.???.???.???", a 15 character string, the following code ends up wrapping the last ? to the next line. But I can clearly see the chline(40) can place a '-' in column 39.

The example code:

  set_text();
  ...
  gotoxy(25,1);
  cputs(ipaddress);
  gotoxy(0,2);
  chline(40);

Ok, I don't know what I did... but this is currently not a real issue..

I added this code to testlib.c so I could see what I thought I expected, which was early wrapping of the characters in the string.

   clrscr();
   gotoxy(0,2);
   cputs("Expected");
   gotoxy(0,0);
   chline(40);
   gotoxy(0,1);
   cputs("<");
   gotoxy(39,1);
   cputs(">");
   gotoxy(0,3);
   cgetc();

But there is no evidence of that, with or without my suggested change to the cputc wrapping condition.
