AutoTap used to develop custom software!
Yes, it is possible! I recently received my AutoTap v3.00 and was pulling my hair out trying to get the provided software to meet my expectations and the inflated claims on the web site. Well I found a .pdf file with the specifications including the full communication protocol of the AutoTap right on their web site for download. I guess you just have to know what to look for. Anyway you can google LDV6S which is the hardware device used for autotap. Also you can purchase just the hardware on their site for about $150 but then both the hardware & software package is only $200 anyway. So goto the autotap site or google and search for product LDV6S and download the manual and youll be on your way. I have connected to the hardware with a terminal program (Procomm Plus) and I also purchased the autotapv3 with the software but an increasingly frustrated with the software since it has been updated but the manual is SO FAR behind the software, it is so frustrating. Enjoy. I would post a link to it but its just a .pdf file so I could'nt.
