Re: modem not working (FINALLY SOLVED)
I found out hat the problem was when I tried to set up a ppp connection
over a nullmodem cable between a mac and a pc.
The pppd manpage says that the Mac serial ports lack a true RTS
output. And usually, the flow control is rts/cts. Adding cdtrcts to the
pppd options file made the modem work.
Unfortunately the connection slibs after a couple of minutes (i.e. very
very slow connection), but my use is limited, so I do not care much about
