Setup:
Dell PIII 1Ghz w/768 MB PC133 RAM
Intel 8xx? chipset motherboard
Dell preinstalled RedHat Linux 7.0
We are using the Digi (www.digi.com) classicboard pci (a 4 serial port pci addon card) with the 4 port DB9 octopus cable to connect an instrument to the computer through one of the serial ports on the digi board. The instrument (a virtual gun), sends a small (8-10 chars)string of data (terminated with an LF) through the serial port whenever the trigger is released or pressed. When the gun is plugged in through one of the serial ports on the motherboard, the reading works perfectly, the events are read as soon as the trigger is depressed or released. When the gun is plugged in through one of the classicboard ports, the message from the gun is delayed, often being read by the software several seconds after the trigger was pressed. Also, data is being dropped because only about 10% of trigger presses are received by the software when it is connected through the classicboard. The hardware sending the serial signal uses no flow control and odd parity.
Anyone else used this card, and/or know of a way to fix this problem?
Thanks,
Kevin
