Sorry, I just get a little hot-headed when it comes to flow control. I've had so many problems in dealing with it in the past ... hmmm.. It does seem that we are talking about slightly different things. I took the person you were responding to to be talking about flow control at the serial port. But as I recall, you were talking mainly about flow control in the TCP code, which doesn't make sense to me because TCP is flow controlled all by itself. I was of course referring to flow control at the serial ports. For me, the magic words to get me boiling is something to do with it not being necessary to have equivalent flow control in both directions. There is no good reason why it should be unequally implemented! All it does is save a few pennies here and there in parts cost (i.e. there isn't any logic on the host to pass the flow-control from the other device down to the software), and later cost people real problems when they don't hook a terminal to the serial port like the designer thought. Then there are a number of terminals which NEED flow control just to operate at 9600 baud. Ones which I'm familiar with are vt100's and the AT&T 5620 (I happen to have had one of each on my desk at various times over the last year). Any micro running a terminal emulator falls into this category. Hmm, wellll, my Amiga seems to do a real good job of keeping up at 9600 baud ... so maybe not ANY micro. [I started to write out some problems we've had here related to UB NIU-180's we've got and have tried to use in a number of ways. But it started to get rather long ... if someone is interested in seeing a horror story I can post it.] -- <---- David Herron -- The E-Mail guy <---- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <---- Vnend would make a perfect toon! <---- He already cleans up after himself like one!
