The 2 "standard" ones, plus an STB 4-com board which is able to share IRQ's. The problem with this solution and adding more ports was that there are only 1 or 2 I/O addresses left that the STB board supports. The standard COM3 I/O address is consumed by by Mach32 video board. This is from my kernel config file: device sio0 at isa? port "IO_COM1" tty irq 4 vector siointr device sio1 at isa? port "IO_COM2" tty irq 3 vector siointr # STB 4-com options COM_MULTIPORT #code for some cards with shared IRQs device sio2 at isa? port 0x1a8 tty flags 0x205 irq 10 vector siointr device sio3 at isa? port 0x1e8 tty flags 0x205 device sio4 at isa? port 0x2a8 tty flags 0x205 device sio5 at isa? port 0x3e8 tty flags 0x205 -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
