I'm sorry that I don't have any pppd-hacking experience, so my answer will be mostly guessing and quite likely, worthless. > Suppose I have a bunch of PPP "packets" and suppose I want to push those > unto a serial line (tty device) which is connected to a modem.

I am guessing that you need to switch the device driver into the "raw" line discipline, meaning that no interpretation is done on the bytes you send. In particular, you don't want "backspaces" and such to do anything special, newlines converted to carriage-return-linefeeds, or anything of this sort. So consider doing the equivalent of "stty raw -echo". But, perhaps if you don't know or don't want to format the PPP headers, yourself, you need the "PPP line discipline". Check out (I just googled) http://www.faqs.org/docs/linux_network/x-087-2-serial.ttys.html. To change the line discipline, look at the source of stty's "line" parameter (or wait for somebody more knowledgable to answer...). -- Nadav Har'El | Wednesday, Aug 3 2005, 27 Tammuz 5765 [EMAIL PROTECTED] |----------------------------------------- Phone +972-523-790466, ICQ 13349191 |Enjoy the new millennium; it might be http://nadav.harel.org.il |your last. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
