Re: Re:Serial port/modem/ppp problem...

["Cj Stremick" <cmstremi@xxxxxxxxxxxxxxxxx>]

The kernel is version 2.2.12.

Do most people typically use scripts for ppp-on/off?  I don't mind taking X
or KDE out of the equation, but I don't have any scripts so I might need
some more help in that department.  I did this about a year ago, but I don't
remember where I got the scripts to modify and use.  Since then, I've waxed
Linux and lost those files, I'm sorry to report.

Windows doesn't really advertise the init string (stupid windows...
Surprised there isn't a "View Modem Initialization String Wizard"...)  I
looked in the inf file that I used to set up the modem under Windows and
used that in Linux.  Problem is, after the default init string, there are
lots of options that are set separately - error correction, etc.  Important
things.  I can't think of a good way to get windows to share exactly what it
send, though.  By looking at the Windows setting, I see that:
  Use FIFO buffers is enabled.
  Error control is enabled
  "Compress data" is selected
  Modulation type is 'standard
  Hardware flow control (rts/cts) is enabled.

crtscts is in the options file, but I'm not sure how to set the 'debug'
option.  Is this a pppd thing?  Do I just put "debug" on a line in the
options file?  Once this option is set, how do I look at the errors?  I
suppose it'll write them to a file or proc...
