This is not necessarily a winmodem, I had an internal ModemBlaster(*not* a winmodem) which also gave the 'busy' error.   I later bought an external and everything worked just fine.  Here is a link that j2 posted in another question thread in which the answer has been finalized.

here is an easy way to determine if your modem will work under linux. If you can - download a program called WvDial at

http://www.worldvisions.ca/wvdial/index.html - this is a very easy program to setup and use and it will determine if your moden works and it will partially configure a script called wvdial.conf that you can use to dial into the internet. Make sure you read the directions.

From what you have said - it sounds like you have a winmodem that will not work under linux. Good luck and ask if you are having any more problems setting up your linux box.

Please try not to post answers unless you know for sure that you have the correct one.  It would be nice to find out what model and brand of modem is involved before bothering to go and install/configure/run some utility that may or may not work or give any further info.  For example, if the modem is jumpered to plug and play, and not set to a com port via the jumpers, this problem can arise. The utility specified here will likely not work at all in this case.  There are easy ways of going about things, and there are long, drawn out ways.  Let's try the easy ways first.

I encountered the same challenge and succeeded in resolving it. I am not, however, very experienced in this area. Keep in mind that I have an ISA modem. If you have different type of modem, some of this information may not apply. Having said that, here's what I think may be going on. First of all, yes, you COULD have a "Winmodem." However, if you don't, there are standard linux tools you can use to fix the "modem busy" problem (IF it is caused by the same issue that mine was, AND your kernel version and installed distribution packages support the following options). Before going into details let me explain that there are a lot of variables in this situation and you have provided very little information. OK. The basic problem is this: you have to set your hardware (the modem card) with the correct port address, IRQ, etc (no conflicts), and then you have to set the linux OS with the same configuration so it knows where to look for signals from your modem. First, work with the hardware settings. If you have a Plug and Play modem, you should find out if you can disable PnP mode on the modem (often software for this purpose is provided on a disk that came with the modem) and whether your BIOS allows you to disable automatic PnP configuration. Read the "PnP HOWTO" and related documents - you will learn why these features can come in handy. If the modem has jumpers on it, you can use them to change your modem (hardware) settings. Alternately, IF you have a Plug and Play modem, you can use the "pnpdump" command line utility to find out some info about possible configurations for your modem, AND generate a script to set the modem card properly at boot time. For setting the OS correctly, first use the "setserial" utility (using the -g switch) to find out the port address and IRQ where the OS is expecting to find the modem. This will also tell you the type of UART chip your modem has. Then you can use the "setserial" command to change those same settings  during a linux session (don't use the -g switch). Once you've done so, newer versions of setserial automatically edit these settings in a configuration file that runs at boot time. Additionally, linuxconfig (if installed, of course) provides a GUI environment for changing what "COM port" (DOS) or "TTYSx" port the OS is set for. In conclusion, abundant documentation (HOWTOs, INFOs, MAN pages, and help files) is usually provided with linux distributions. Sometimes you just have to make yourself study the materials in order to solve a problem. Some basic knowledge is required to even understand what I've said here and I apologize if I've unintentionally gone over your head. Just remember to give as much information as you can when you ask a question and it's likely you will get better answers. There is a lot more to this issue but you'll have to do your homework and revise your question to get any more out of me : )
