- Regardless of *what* Dell said, the original poster asked (see subject line)
- "Can I Upgrade a 16450 UART to a 16550a", NOT "what kind of UART does
- a Dell 325D have..." or "What will it take to put a 16550A UART in a Dell
- 325D...", Jim answered the original poster's question, not the question the
- poster *should* have asked...'nough said...

- Ummm...excuse me Dave, but the original question *was* can one chip be
- replaced with another...as far as being computer literate, I know many
- people who write software for a living, even down to the device driver
- level, and many who have andvanced degrees in computer science who have
- no idea what kind of UART a Dell 325D has and could really care less...I guess
- this makes them COMPUTER ILLITERATE??? And I guess the fact that somebody
- tinkers with a PC and runs a few programs makes the computer literate???
- give me a break!!
