We have a PC/Xem card running 56 ports. We have been very pleased with the performance, however, we have experienced some "output stalled" messages that we believe is contributed to the PC/Xem card. The other thing you may want to consider is througput rates and the number of ports it will support. The PC/Xem card will support 64 ports, but you will do good to get 38400bps throughput on all 64 ports. You certainly won't get 57600bps. Even the Digi techs will tell you that they only guarantee 57600bps on 32 ports. I suggest you check-out the Comtrol Rocketport. It is also supported by BSDI. It will support 128 ports! They guarantee a throughput of 230,400bps full duplex on 32 ports. They also say it will perform at 57,600bps across all 128 ports! The Digi PC/Xem card has one 16bit processor, but the Rocketport has 4 16bit 36mhz processors. Besides all of that, it is *significantly* cheaper than Digi's PC/Xem card and so are their equivalents to the Ports/16em port boxes. Now, I have not actually used one yet, but as you can see, I'm already sold on the product. We plan to purchase one in the next couple of weeks. Ask them to send you their Product Comparison book. Make sure they send you the Unix comparison rather than the Novell comparison. They used two different flavors of Unix for their testing (SVR4.2 and SCO). *David*
