Hello,
I found a problem with ppp daemon (QNX 4, TCP runtimes 4.24 and 4.25).
pppd with options “connect …” uses programs like chat for establishing
a connection. According to the documentation pppd supports the similar
option disconnect, but it does not work - if I send any of the signals
SIGINT, SIGHUP, SIGTERM to pppd, pppd invokes only the script
/etc/ppp/ip-down, but no script specified by disconnect option
(so if there is no ip-down, nothing is invoked).
Disconnect script is (or should be) used for clearing a X.25 call in PAD -
ppp is tunelled over X.25.
The general script ip-down can serve for this purpose only if there
is only one ppp profile (ip-down must run chat with redirection of
standard inputand output to the serial line), but I need several ppp
profiles (over different physical lines).
I cannot upgrade tcprt to 5.0 and I would prefer to work with
“pppd disconnect …”.
Thanks for answers.
Martin
