Contributed by &a.alex;.6 June 1996. The Cyclades multiport cards are based on the cy driver instead of the usual sio driver used by other multiport cards. Configuration is a simple matter of: Add the cy device to your (note that your irq and iomem settings may differ). device cy0 at isa? tty irq 10 iomem 0xd4000 iosiz 0x2000 vector cyintr the new kernel. Make the by typing (the following example assumes an 8-port board): # cd /dev # for i in 0 1 2 3 4 5 6 7;do ./MAKEDEV cuac$i ttyc$i;done If appropriate, add entries to by duplicating serial device (ttyd) entries and using ttyc in place of ttyd. For example: ttyc0 "/usr/libexec/getty std.38400" unknown on insecure ttyc1 "/usr/libexec/getty std.38400" unknown on insecure ttyc2 "/usr/libexec/getty std.38400" unknown on insecure [...] ttyc7 "/usr/libexec/getty std.38400" unknown on insecure Reboot with the new kernel.
