Um, you were using PPP, correct? And you are seeing missing lines, dropped characters, etc? You won't get this from broken flow control, unless you are using a UDP-based communications tool. If you are using user-mode PPP, "HDLC" errors are the giveaway for flow control problems. > Luigi -- ]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ ]] Genesis Software genesis@gsoft.com.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control.
