Pretec's fax/modem also supports the V.80 application interface, so it is capable of operating with any H.324 video phone system. This functionality provides you with affordable video conferencing over ordinary telephone lines. By adding an optional CompactFlash adapter, the card becomes a PC card for use with most notebook computers and instruments with PCMCIA slots. Pretec's CompactModem works with Windows 95, 98, NT, and, most importantly, Pocket PC and Windows CE environments.
