My experiences with public or private data nets using X.25 is that under congestion conditions, X.25 does NOT recover from the problems causing resets while TCP and other end/end transport protocols often do recover. Consequently, most inter-computer applications use some kind of end/end protocol with retransmission (and, of course duplicate detection) above X.25. I took the earlier comments on X.25 to imply that raw X.25 is sufficient. I would have to say that my experience has been otherwise, except for terminal to host applications in which the user recovers from problems by re-typing his input (which behavior is also appropriate for noisy, unprotected dial-up access to PADs...). Do we have a difference of opinion? Vint
