Installing PCI modem in machine with 4 serial ports (HELP!)
Hi - I've got a little computer that has four serial ports built-in to the motherboard. I want to add a PCI modem (USR 5610B) and am having a devil of a time. I know this modem works since I've used it (well, another one just like it) in another machine no problem. Here's the computer's board: http://www.orbitmicro.com/products/embedded%20boards/via/EBC-569.htm The last time I did this it just worked. However, this bit from the Handbook has me concerned: --- These are the four serial ports referred to as COM1 through COM4 in the MS-DOS/Windows world. Note: If you have an internal modem on COM4 and a serial port at COM2, you will have to change the IRQ of the modem to 2 (for obscure technical reasons, IRQ2 = IRQ 9) in order to access it from FreeBSD. If you have a multiport serial card, check the manual page for sio(4) for more information on the proper values for these lines. Some video cards (notably those based on S3 chips) use IO addresses in the form of 0x*2e8, and since many cheap serial cards do not fully decode the 16-bit IO address space, they clash with these cards making the COM4 port practically unavailable. Each serial port is required to have a unique IRQ (unless you are using one of the multiport cards where shared interrupts are supported), so the default IRQs for COM3 and COM4 cannot be used. --- I rarely use modems, and am even less proficient at messing around with IRQ stuff. What I'm concerned about is that it seems to say you can only have 4 serial ports (COM1 - COM4) total... which means I'm kind of screwed. I've tried disabling all of the serial ports via the BIOS, but it doesn't help... If anyone out there has any light to shed on how to get this working I'd appreciate it.

Because the modem is inside the computer on the PCI bus, and not attached to one of the two serial ports on the outside of the motherboard (each of which does double duty as two COM ports), it is NOT any of COM 1 through COM 4. In FreeBSD (in 5.1 anyway), here are the equivalent devices: WindowsFreeBSD 5.1 ------ COM 1 - /dev/cuaa0 COM 2 - /dev/cuaa1 COM 3 - /dev/cuaa2 COM 4 - /dev/cuaa3 A PCI-card modem, with its own port on its card - /dev/cuaa4 -Steve D New Mexico US -- Life is full of answers, if you don't care what the questions are. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
RE: Installing PCI modem in machine with 4 serial ports (HELP!)
To start with you are very light with details about your environment, like what version of FBSD you are running and when you say the modem works, you failed to say if it worked in an FBSD system or MS/Windows system. For your info many of the PCI modems on the market are manufactured specially for MS/windows and are missing the onboard controller. The controller function is performed by the modem driver you have to load into MS/windows. If you have one of those winmodems but it back in your windows box where it belongs. Lets assume your modem has the onboard controller. Have you reviewed the boot log /var/run/dmesg.boot file? It may be found as (unknown) in that case it may be an winmodem for sure, or you have installed FBSD on an pre Y2K PC and it's bio's are giving FBSD problems. Adding device puc to your kernel source and recompiling your kernel will fix this problem. The other condition is the your modem is found at boot time and is moved to sio4 which is really com5 which in not defined in the 4.x versions of FBSD. sio0: Zoom PCI Modem port 0xe400-0xe407,0xe000-0xe0ff,0xdc00-0xdcff mem 0xe200- sio0: moving to sio4 sio4: type 16550A Sio4 is internal device cuaa4. For some unknown reason this device is not in the device table for 4.x versions You have to create it manually by doing the following commands. cd /dev ls -l /dev/cuaa4shows as not found sh MAKEDEV cuaa4run script to make the device. MAKEDEV must be in caps. ls -l /dev/cuaa4now shows it's there Device cuaa4 is the device you tell user ppp to use to connect with your PIC modem. If you are running 5.x version of FBSD then you do not have to makedev it auto in 5.x. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Philip Hallstrom Sent: Monday, January 05, 2004 1:03 PM To: [EMAIL PROTECTED] Subject: Installing PCI modem in machine with 4 serial ports (HELP!)

RE: Installing PCI modem in machine with 4 serial ports (HELP!)
Oops... you're right. FreeBSD 4.9-RELEASE. Never tried it with windows. However, I've put this exact card into a different server (with only two serial ports) and it is found as sio4 and works perfectly. In the broken machine the boot message says what you have below, that it's moving it to sio4, and I did make the devices (did the same things I did for the machine that works) but still nothing. For now I'll just use the other machine, but it's irksome... -philip To start with you are very light with details about your environment, like what version of FBSD you are running and when you say the modem works, you failed to say if it worked in an FBSD system or MS/Windows system.
