Check the AX25-HOWTO section 6.1.1.1 ("Configuring for Dual Port TNC's")
<http://www.tldp.org/HOWTO/AX25-HOWTO/x495.html>

(the short form:)

# /usr/sbin/mkiss -s 9600 /dev/ttyS0 /dev/ptyq0 /dev/ptyq1
# /usr/sbin/kissattach /dev/ttyq0 port1 44.135.96.242
# /usr/sbin/kissattach /dev/ttyq1 port2 44.135.96.242
