-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi John, This is a reply to a message to the COMEDI list from March. I'm looking for a quadrature decoder card to use with Linux, using the COMEDI API if possible. The PCI-QUAD4 card from MCC suits well my application, I just read your old posting where you mention a serious problem. Could you resolve that problem or shall I better forget about this card?
