Just FYI, the reason you get a "appear to have received our own echo-request" is likely because after the connection is lost the modem goes back into "command" mode where it echoes back anything you type (or ppp sends). -- Jens B.

Re: ppp error question
First, last night was the first time I have seen that error. Been using it for months. No change on the ISP end. Second, /dev/modem is symlinked to /dev/ttyS1. So in my case /dev/modem is right. I also tried /dev/ttyS1 just in case.

I had a somewhat similar problem with an internal modem. Apparently the on-board micro can crash. Try using minicom to send 'ATZ'. If this doesn't work, hard reset is the only way out. I considered soldering a reset switch into the modem, but I bought a new one instead. -- John Hasler [EMAIL PROTECTED] (John Hasler) Dancing Horse Hill Elmwood, WI -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .

I didn't get a locked up machine right away. It would only hang the connection. Eventually the modem got so fratsed that it could not be recovered without a reboot. That was when I went looking for a new modem. The error message is a result of having LCP echo frames configured in your options file (as a keep alive for the link). When this error would happen to me, my ISP would still show me as logged into the system, even though neither of us could ping the other. Removing the LCP echo from the options file only made the errors more bizzar.

I'd say the problem is somewhere else... You shouldn't use /dev/modem unless it's a pcmcia modem or something. Use /dev/ttyS? instead.

ppp error question
I received this last night: Excessive lack of response to LCP echo frames connection terminated What does this mean? I had to reboot because my box quit seeing my modem. setserial would say /dev/modem, unknown UART, 0x2f8 irq 3 with `setserial /dev/modem`. It is an internal Best Data uses dip switches and has served me faithfully for many moons. Is there some way to reset a modem without a coldboot (which this required, reboot did no good)? -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
