Use hardware flow control (if it works). Try turning it on in the modem, and in the driver (FAS?). Then try downloading then uploading a file using zmodem at both a high speed and a 2400 baud connection - with the DTE locked at either 19200 or 38400. If you get a flawless transfer (no errors) then you should be all set - however - if flow control isn't working - you will sure enough see errors.. -- Larry Snyder, Northern Star Communications, Notre Dame, IN USA {..!uunet!mailrus!iuvax!ndcheg!nstar!larry, larry%nstar@ndcheg.cheg.nd.edu} backbone usenet newsfeeds available Public Access Unix Site (219) 289-0282 (5 high speed lines)
