Re: TS4 I/O buffer buildup

["Bob Scott" <rlscott@xxxxxxxx>]

Jim,

Mark Brown recommends a Byte Runner Technologies board.  He
uses their model PCI -100H which has a current cost of $36.00 and which
represents excellent value and performance.  This board also looks good to
me because it is a PCI card, has a 128 byte buffer and can run as fast as
921.6 KBaud.  I suggest that this might be the best $36 you ever spent.

                 http://www.king-cart.com/cgi-bin/cart.cgi?store=byterunner

         Then select Single serial cards in the 32-bit PCI Cards column.
