g'day folks. i did a google search on the group for my problem and no
luck so i thought i'd post it, maybe some of you tangled with this.
basically, pppd says "/dev/cua00 busy", chat sends "at", expects "ok",
receives nothing, aborts. HOWEVER, minicom on /dev/cua00 works fine, i
can talk to the modem, i can dial, everything. what's even more
frustrating, the pppd conf (/etc/ppp/options, /etc/ppp/isp.chat,
/etc/ppp/peers/isp) are IDENTICAL (in fact are copied over) to the one
on another machine where the modem was previously installed and
worked. since i use a custom kernel on the new machine i thought i
screwed something up and reverted to GENERIC. nada, same problem, pppd
can't do anything with /dev/cua00, minicom has no problem. echo
"atdtXXXXXX\n" > /dev/cua00 makes the modem go off-hook and then
on-hook again (i can hear the line relay clicking twice), which is
normal, i say, since echo can't control the DTR and the modem is set
up to hang up and return to command mode if DTR is low. any ideas?
