Fair enough.

Okay, but I'm afraid that doesn't quite compute to me, maybe you could
clarify:
- If it's flushing on every character, then why is the output speed
acceptable when using fputs/fprintf or anything except fputc? i.e. why
do I get the 300-baud-modem emulation only in a few cases?
- Why does it take so long (10ms) to flush the stream?
- Why does it only happen with 'tty' set?
Sorry if I'm being dense. I was also going to ask what the heck newlib
was but I figured that out on my own. :-)
Thanks,
Brian
