- I just purchased a high speed modem (14.4K from Boca) for my Dell
- 325D. I was almost sure Dell would have put a good uart in the
- machine, but it turns out it's only a 16450. Naturally, I'm losing
- char.s with high-speed transfers, especially with a loaded machine
- (I'm running Linux --- a Unix clone).
-
- Is it possible to upgrade the 16450 to a 16550a? (I assume that will
- help the problem; correct me if I'm wrong.)
-
- [I tried asking the representative a Dell, but, when he answer my
- question of "What kind of uart is in the machine" with "You have a
- VLSI chip," I gave up.]
-
- Thanks in advance.
