It's probably better to not run in background.

Something simple like this will work (crontab with */10):

#!/bin/sh
cd /home/bbbs

# incoming fido
./bbbs bogus w > /dev/null 2>&1
./bbbs btick > /dev/null 2>&1

# outgoing fido
./bbbs bogus r > /dev/null 2>&1

# notify node 2 to rescan outbound
touch work/rescan.2
