I an not sure, what actually you are interested in, but you can indeed
use zaptel to create hdlc link, you don't need asterisk in this case
at all, only zaptel drivers. Compile them with
CONFIG_ZAPATA_NET defined in zconfig.h. To assign timeslots for hdlc
link you should use nethdlc directive in zaptel.conf. After starting
of zaptel this will create some (depending of your settings in
zaptel.conf) linux hdlc interfaces which you can configure with
ordinary sethdlc utility. As a result you will be able to use sockets
to send hdlc packets.

I recommend you to use trunk version of zaptel to work with hdlc,
stable has at least one bug related to hdlc.
