I've just figured out that my Mtek Taicon Modem is actually a TAICOM modem. On the PCB the follwing ID shows M56PVS-SOFT / VER 3.0 99'10 / PN 01090013. This driver was found at www.taicom.com.tw/download/modem/mp56pvs-soft.php. I have not tried it yet but I'll do it as soon as I end this post. Good Luck fellows!
