Jason I think you are confusing RAT and VAT. RAT only works with full duplex cards - I made that (erroneous) design decision when RAT-4 work started. AFAIK VAT has always supported half-duplex cards and half-duplex operation with full duplex cards. Work on VAT stopped around 95-96, so there are no "modern" versions, only maintenance has gone on since then. There was a problem with the freebsd-ports version of VAT misdetecting full duplex cards as half-duplex, but it still worked (http://www.FreeBSD.org/cgi/query-pr.cgi?pr=23618). I shall re-check the freebsd ports version tonight to be sure unless. Cheers - Orion To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
