- As I shop for a serial card with an NS16550AFN UART, I have come
- across a couple which were 8-bit cards. Please excuse my ignorance of
- the subject, but shouldn't that chip be on a 16-bit card to perform
- optimally? As I understand it, (which is not well at all) the 8250
- was an 8-bit chip, but the 16450 and 16550 are 16-bit chips (the 16550
- having a 16 byte FIFO buffer). So there's the cause of my confusion:
- wouldn't putting the 16550 on an 8-bit card be defeating the purpose?
