- It isn't a matter of price (see above). And it's not true that a
- 16550 is *required*, since in most cases TE/2 does a pretty good job,
- it's just that it's buggy. I have every right to complain if software
- just doesn't measure up. I have difficulty believing that it's
- *impossible* for a 386-class machine running an OS/2 comm program to
- do 9600 baud transfers reliably w/o a 16550 when such a machine under
- DOS can comfortably do 38400+ (even 115K using appropriate software) baud
- transfers. Sure, a 16550 UART is great; but I'm sick of programmers
- insisting that "all that's necessary to make my program work
- adequately is buy some more hardware". The words lazy, incompetent,
- or *beta* come to mind, but not "production quality". There's a
- difference between complaints that mask impossible demands ("hey, why
- can't my 8088-class machine run OS/2?") and complaints address
- someone's refusal or inability to create a decent software product
- given adequate hardware. Telling someone 10 years ago that a 5 MIP
- machine wouldn't be able to handle 9600 baud serial communication
- would probably have result in some strange looks.
