"Modem Is Busy" error when trying to connect to the Internet with kppp

I recently bought a Smart Link 56K Voice Modem because the box said it had Linux support. It works well on Windows 2000, but I couldn't get it to work with Mandrake 10.0 (with Kernel 2.6.3). I downloaded the updated drivers (went from slmdm-2.7.15.tar.gz to slmodem-2.9.10.tar.gz). I followed all of the instructions from the README. After struggling for about a week, I finally got Linux to detect my modem. The only problem now is that everytime I use kppp to connect to the internet, I get the error "Modem is busy." I try to query the modem and it says "Modem is busy". Does anyone know what this means and how I can fix it? Any help is much appreciated.

In kppp, this message is sent when an attempt to get/set the serial port "stty" parameters fails. (It's similar to the "Input/output error" one may get when trying to use "stty -F /dev/ttySx"). To get a few of these stty parameters, the true address of the port must be known to the driver. So the driver may have the wrong address. The setserial" command will display what the driver thinks but it's likely wrong in this case. So what the "modem busy" really means is that the serial port (and the modem) can't be found.

If you have a pci modem, then use one of these commands: lspci, or cat /proc/pci, or dmesg to find the correct address and irq of the modem's serial port. Then check to see if "setserial" shows the same thing. If not, you need to run a script at boot-time which contains a setserial command that will tell the driver the correct address and irq. The reason that the driver has it wrong may be due to failure of the kernel to understand the lspci data correctly. You might notice this in a boot-time message.

Thank you. I now get that part, but I have no clue what the "setserial" is, nor where to find it.

http://setserial.sourceforge.net/

It should be in your system already. Mine is located here: /bin/setserial
