My PPP connection appears to run as it should, but it also shows about a 5-10% packet error rate. Running pppstats, I can see batches of 7 or 8 errors happening at a time during, say, an inbound FTP. During these periods the modem shows as mostly idle. Possibly it's waiting for a TCP timeout/retransmission. I am running a U.S. Robotics Sportster modem, 14.4Kb, dialup into an Annex box. I have 16550s in my Pentium 90. I'm running a Logitech bus mouse and XFree86 3.1.0 at the time. These errors and timeouts slow things down. What's the use of spending the bucks to run at 28.8 if I'm only going to spend most of my time waiting for TCP (or maybe PPP) timeouts? Is anybody else seeing this? Even suggestions of what to tear into would be welcome. I am comfortable with banging on kernel source if I know where to start. If anyone wants more specific information, just ask. Mike O'Brien
