The QuadraLink cdev allows you to "shadow" one of the QL ports to either the printer or modem port. This still limits you to two active serial ports at a time. Apps that recognize the card can have all ports going at the same time (great for BBS's). The QL init software creates eight I/O drivers for each QL card that it finds (four input, four output). If you want to open a serial port on the card, and you know the card is in slot $C, then the output driver name would be "QuadraLink Port 1OutC" and the input driver name would be "QuadraLink Port 1InC". The "1" is the port number (from 1 to 4) and "C" is the slot number (from 9 to E). Finding the card is a simple matter of examining the NuBus slot resources and looking for the name "QuadraLink" Hope this helps... Hank van Tunen
