- If your machine has a 16450 UART, why don't you spend $10 to $15 dollars
- for a 16550 AFN? Then you won't have those problems you are having.
- The 16550 AFN will fit into the socket where your 16450 is. Any
- multitasking enviroment needs a 16550 AFN to work well with high speed modems,
- that's just the way it is. So either except it or quit complaining.
