Nope... I very rarely experience problems with IIJPPP that can't be traced to the terminal server I'm dialing into crashing or a line problem. (Damned BT :( ) > Is the interrupt level extraordinary? I should say so. From my machine, which for a while was downloading a large file at 3.1K sec with a 115200 baud DTE rate to a 28k8 modem. I'm using a 16550 COM port: gary@palmer:~> vmstat -i interrupt total rate clk0 irq0 784266 102 rtc0 irq8 982565 128 fdc0 irq6 1 0 sc0 irq1 28054 3 sio0 irq4 106707 13 sio1 irq3 910720 118 ed0 irq10 1 0 Total 2812314 366 The modem is on sio1... My IRQ rate (total) is 366/sec on average. > If so, what can I do - is it a hardware problem? Possibly. Do you have a FIFO'd COM port (a 16550) or one of the older, non-FIFO'd ports? I don't think (however) that this problem is tracable to the IRQ's... Have you tried updating the kernel & ppp binaries? Gary
