 Thanks for the quick reply.  I decided to do a fresh install of
 8.0-RELEASE amd64 before I re-ran the test.  Here are the details:
 
 # uname -a
 FreeBSD lab1 8.0-RELEASE FreeBSD 8.0-RELEASE #0: Sat Nov 21 15:02:08 UTC 2009     root at mason.cse.buffalo.edu:/usr/obj/usr/src/sys/GENERIC  amd64
 # sysctl hw.usb.ucom.debug=15
 # tip ucom1
 connected
 # paste 160 "a"s followed by a newline (may take several attempts when debugging is enabled)
