I used to run a multi-line BBS (Wildcat!) and may still have two multi-port serial interfaces. I know that one has eight com ports and the other can support 64 but only has 32 ports installed.
Give me a day or two to dig them out (if I still have them) -- they were both working fine when removed from service and Drivers are available (just checked their website). PCI bus.
