No! Don't do it. In most cases, a program will read some characters
from the port. And must fight with the above "cat"! If you can not
solve the problem locally (there were could suggestions to the originate
question), I think the best central approach will be in an rc script:
while :; do sleep 30000; done </dev/tty1a &
