Is it expected? I wonder if that's some sort of reference to carrier detect being wired wrong on whatever device or adapter you have connected to your serial port. However, I can't find this string referenced anywhere in the kernel source code for RELENG_6. An (admittedly bad) egrep shows: $ egrep -r "Got .+ signal" /usr/src /usr/src/contrib/amd/amd/nfs_start.c: /* Got a signal */ /usr/src/usr.bin/make/job.c: * Got a signal. Set global variables and hope that someone will /usr/src/usr.sbin/bluetooth/bthidd/bthidd.c: syslog(LOG_NOTICE, "Got signal %d, total number of signals %d", /usr/src/usr.sbin/bluetooth/hcsecd/hcsecd.c: syslog(LOG_DEBUG, "Got signal %d, total number of signals %d", /usr/src/usr.sbin/bluetooth/sdpd/main.c: log_notice("Got signal %d.

Consider using uart(4) as a possible alternative, but depending upon the answer to the above question, this might not be applicable. I wrote some directions on how to get uart(4) to work, and one caveat I found when attempting to use it.
