1. General Information and Hardware Requirements 1.1. Introduction The ACP Modem for Linux is a software based modem. Support software for the ACP modem is composed of a loadable kernel module and a user level application. Together these components support direct connection to public switched telephone networks (PSTNs) and support selected countries world wide. Refer to Section 6 of this document for the supported country list. The modem also supports the standard communications port inte

Linux ACP Modem (Mwave) mini−HOWTO 1.6. Which Systems are Supported This version of the ACP Modem driver supports the IBM Thinkpad" 600E, 600, and 770 that include on−board ACP modem hardware. 1.7. Features of the Modem The ACP Modem provides the following features: • Standard asynchronous COM port interface (NS16550A UART compatible) operation • Bell−103/212A, CCITT−V.21/V.22,V.22bis protocols with data from 300 to 2400 bps • CCITT−V.32 protocols with data rates of 4800, 9600 uncoded, and

2. Compilation, Installation, and Startup 2.1. Prerequisites • A 2.2.16 series (or later) Linux kernel source tree • An appropriate set of module utilities • gcc version 2.7.x or later If you are building the ACP Modem driver along with the user space application, you need to have a complete Linux source tree for your kernel, not just an up−to−date kernel image. 2.2. Building and Installing Source 1. Use tar xzvf mwavem−yyyymmdd.tar.gz to unpack the distribution. 2. Change directories with

Linux ACP Modem (Mwave) mini−HOWTO Country information (including access codes) are listed in the mwavem.conf file. For example, for France the following section is present: [Telephony\Country List\33] CountryCode=00000021 Name=France SameAreaRule=0FG LongDistanceRule=0FG InternationsalRule=00EFG To set France to be your configured country in the [WORLDTRADE] section of mwavem.conf, set Country=33 2.4.

Linux ACP Modem (Mwave) mini−HOWTO The following arguments are not persistent from boot to boot (i.e. We are not saving them in the BIOS). • mwave_3780i_irq=5/7/10/11/15 This parameter allows you to configure the IRQ used by the DSP if the DSP IRQ was not set and stored in BIOS by the Thinkpad" configuration utility. • mwave_3780i_io=0x130/0x350/0x0070/0xDB0 This parameter allows you to configure the I/O range used by the DSP if the DSP I/O range was not set and stored in the BIOS by the Th

Linux ACP Modem (Mwave) mini−HOWTO during the build process. 2. Setup the serial driver to recognize the UART provided by the ACP driver. setserial /dev/ttyS0 autoconfig NOTE Substitute /dev/ttyS0 to match the serial port you have configured the DSP to use. NOTE You may wish to create a symbolic link from your modem device to your serial device for convenience. Example: ln −s /dev/ttyS0 /dev/modem The ACP Modem is now available for use by your favorite dialing application. 2.4.2. Running AC

3. Resolving Installation and Configuration Problems The following sections list solutions to possible problems you may experience. 3.1. DSP Does Not Start In order to recognize memory above 64 Meg, it may be necessary to append the "mem=" option to the kernel command line. If you are using LILO for your boot loader, you would do this in the lilo.conf file. For example, if you had a machine with 128 Meg you would type: append="mem=130496K" NOTE Your statement must reflect 576K less than you ac

Linux ACP Modem (Mwave) mini−HOWTO IRQ 4, I/O address 0x3f8 (if using ttyS0) For dual boot systems we recommeded that you use the Thinkpad" Configuration Utility on Windows NT or DOS to configure these system resources. Windows NT Thinkpad Configuration Utility Notes: (Under the Internal Modem −−> Advanced selection) 1. Set IRQ sharing to disabled 2. Set 1st IRQ to your DSP IRQ (10 is recommened) 3. Set 2nd IRQ to your UART IRQ (i.e. ttyS1 is equivalent to

Linux ACP Modem (Mwave) mini−HOWTO setserial /dev/ttySx The above command should return the following for serial port 1: /dev/ttyS1, UART: 16550A, Port: 0x2f8, IRQ: 3 The port and IRQ numbers should match the information placed in the syslog by the ACP module when it was loaded: kernel: Mwave Modem, UART settings IRQ 0x3 IO 0x2f8 If the information returned by setserial indicates that the UART is 'unknown' or if the IRQ and I/O resources do not match what you have in the syslog, you will need

4. Debugging Tips 4.1. Error Logs Errors encountered by the ACP Modem device driver or application are logged using the syslog utility. 4.2. Tracing The ACP device driver supports a debug argument to enable the generation of trace information. The command for this debug is listed below. You can also access several of the variables listed below in the mwaved script. insmod mwave mwave_debug=0x0f Where the following debug trace information is selectable: 0x01 ACP Modem Device driver entry
