I use an 8 serial card with 16450s, seems to me it'd be trivial to chop them off, solder suck the pads, & solder on 16550s .... whay I use is this: # Card Name: Decision 8801. # Manufacturer: Decision Computer Int. Co., Ltd. # Comment: 8 Port Hardware documented in /sys/i386/isa/isa_8com.h # 8 * NS16450N, Selectable: irq 2,irq 3,irq 4,irq 5,irq 6,irq 7. options "COM_MULTIPORT" # Multiport support in sys/isa/sio.c device sio0 at isa? port 0x2A0 tty flags 0x0301 # irq 4 device sio1 at isa? port 0x2A8 tty flags 0x0301 # irq 4 device sio2 at isa? port 0x2B0 tty flags 0x0301 # irq 4 device sio3 at isa? port 0x2B8 tty irq 4 flags 0x0301 vector siointr device sio4 at isa? port 0x1a0 tty flags 0x0701 # irq 5 device sio5 at isa? port 0x1a8 tty flags 0x0701 # irq 5 device sio6 at isa? port 0x1b0 tty flags 0x0701 # irq 5 device sio7 at isa? port 0x1b8 tty irq 5 flags 0x0701 vector siointr I have more info in my /sys/i386/isa/isa_8com.h which I can mail you, if you want. (The card was about 300 DM about 3 years ago, (2.35 DM ~ 1 UK Sterling) Julian S
