Here is an update to my earlier message: Everything I've been able to turn up on Google suggests that this is a flow controll problem so I tried setting the port speed down to 38400 to reduce the possibility of overruns. Sure enough uploads lasted much longer before the modem dropped the connection so it seems like I may be on the right track. I checked the primary modem (the serial one) and it IS set to use hardware flow control and my /etc/ppp/options file does contain "crtscts" and "modem" which should cause pppd to use hardware flow control as well. The only things I can think of are that either pppd is ignoring these options or a cable problem. I'll be picking up a new cable tonight but I'm not really sure how to verify that pppd doesn't have a bug that is keeping it from using flow control properly. I'd really appreciate hearing from anyone who has large uploads working at full speed on woody via ppp or anyone who is running into the same problem. -- Ray
