The reason for internal ones is that the box was needed urgently (its a permanently connected internet gateway) and the bits lurking around didn't include a multi I/O card with 16550 UARTS. The internet modem has been running well on cuaa0 for weeks, but I need to get the second modem on cuaa1 configured so it can connect the first LAN to a Win2000 / Win9x LAN a few suburbs away. The motherboard is ISA / VESA, so there's no onboard COM ports to cause conflicts, and both modems have jumper IRQ configuration. I checked the kernel configuration file for tun & ppp devices, there are two of each so I figure that won't need any modification. (1) Despite the first modem working well, the output of dmesg looks weird to me. sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0 sio0: type 16550A sio1: configured irq3 not in bitmap of probed irqs 0 sio1 at port 0x2f8-0x2ff irq3 on isa0 sio1: type 16550A ... ... unknown0: at port 0x3e8-0x3ef irq5 on isa0 Notwithstanding dmesg, the NetComm modem is set by jumpers for COM1 / IRQ4 (plug & pray is disabled) and both ppp.conf & minicom both recognize it on cuaa0, so what gives here ?? To get the user-ppp working for the second modem I "borrowed" some ideas from the ppp.conf.span-isp example file, which suggests its OK to add a /dev/cuaa1 entry to the set device line, and an entry for the second host / phone number etc. Looking at ps -auxw when I attempt to run the second modem suggests that ppp looks at the first /dev entry, and if thats busy it goes to the next in the list. The second modem is a slightly earlier Netcomm ..... it dials out readily with minicom, but when I use either "ppp -ddial " or the "ppp / term" stuff, it just gets to "ppp ON> " and sits there all day...... ppp.log says "/dev/cuaa1 doesn't support CD" There doesn't appear to be any mention of this message in the mailing list archives but I suppose the only thing it could mean is "carrier detect", from which I gather its trying to tell me it doesn't detect dialtone ....... but if that's the case why does minicom have no such problem ?? I don't think I can use minicom for anything but testing as the link has to run TCP/IP networking & as far as I can tell thats not what minicom was designed for. I did consider trying to run kernel-ppp for the second link, but there's not a lot of explicit info on that anywhere I could find. Anyone have some clues on what to do here ??
