Change FIFO Bytes on Serial Adapter Card Startech PEX2S553 on Optiplex 3040
I have purchased 14 Optiplex 3040 with a card adapter to obtain 2 additional serial ports (Startech PEX2S553). This card is working with 128 bytes FIFO and my banking periphals can´t establish communication with the optiplex pc. Is it possible limit to 16 bytes fifo like other cards ??
