   serial ports galore

   INT 14H allows you to specify the port in DX.   
      
   http://www.ctyme.com/intr/rb-0811.htm   
      
   It starts at 0 = COM1, meaning 65535 = COM65536.   
      
   That's a shitload of theoretical COM ports the   
   manufacturer can provide.   
      
   Any reason why PDOS shouldn't just accept an   
   fopen("COM54321", "w+b");   
   and see what the port has to offer?   
      
   Does it make sense to match it to internet port   
   numbers, so I do an fopen("COM80") or COM81   
   to see if any HTML terminal is trying to connect   
   to me?   
      
   Or should I channel such things down COM1 and   
   send an ATinport=80 and ATA?   
      
   I guess the objective is to have a multi-line BBS   
   that still enables dial-out.
