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 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
