Was cua the one which would return without having Carrier Detect? My problem is that if I use /dev/ttyS? instead of /dev/cua?, in the /usr/doc/ppp/examples/secure-card expect script, it doesn't work. That script has stuff like system "stty 19200 -echoe -echo raw < /dev/cua3 > /dev/cua3" When using /dev/ttyS? instead, it won't return, whereas using cua does. Would you know how to fix this problem so that I can use /dev/ttyS? instead in scripts like these?
