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. Total number of signals received %d",
What version of FreeBSD are you referring to?

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. Those docs are here:
