Voice: 508 433 6936 >dufault@hda.com Fax: 508 433 5267 Boca Research has line of multiport serial boards which work fine with the sio driver. I've got a 4 port version, expandable to 8. They also a 16 port version. I'm not sure about them having a 32 port version. Here is the dmesg output from the 1.1.5.1 box that has the 4 port on it: sio2 at 0x240-0x247 flags 0x585 on isa sio2: type 16550A (multiport) sio3 at 0x248-0x24f flags 0x585 on isa sio3: type 16550A (multiport) sio4 at 0x250-0x257 flags 0x585 on isa sio4: type 16550A (multiport) sio5 at 0x258-0x25f irq 15 flags 0x585 on isa sio5: type 16550A (multiport master) and the kernel config lines: # BocaBoard 1004 (4-port serial board) options "COM_MULTIPORT" device sio2 at isa? port 0x240 tty flags 0x585 device sio3 at isa? port 0x248 tty flags 0x585 device sio4 at isa? port 0x250 tty flags 0x585 device sio5 at isa? port 0x258 tty flags 0x585 irq 15 vector siointr You might ask Bob Wilcox about the stuff that he uses. He has used the Boca Boards in the past, but I'm not sure what he uses now. I've also used FastComm 4W (a 4 port) boards in the past. They seem to work just fine. I haven't done any torture testing, though. -Mark Taylor mtaylor@cybernet.com
