This file lists the main functional enhancements, additions, bug fixes, and known incompatibilities for the SM 56 PCI Modem. 3 Com Network Interface Card (NIC) Interrupt Sharing Problem After investigating a periodic (approx. once every 8 seconds) desktop freeze (no mouse response for a second or so) we found that the offending device was actually 3 Com's 3 C 905 B-TX NIC. This NIC/driver has an interrupt sharing problem. The problem shows up with any devices that share the interrupt with it, including various modems (AC-Link and PCI) and PCI display adapter cards. Be aware that the same sharing problem may exist with other members of 3 Com's 3 C 905 xx family of NIC boards and software. Telephone Answering Machine Local Message Playback The SM 56 PCI Data/Fax/TAM modem supports telephone answering machine (voice message recording and local / remote message playback), it does not support other voice features such as speakerphone (Data/Fax/TAM/Speakerphone modem does this).
Local message playback through the PC's sound system can be done with the Data/Fax/TAM model. However, some telephony applications may query the modem for speakerphone support, and, on finding that speakerphone is not supported, will not play the message back locally. This is an issue for the telephony application provider. Local TAM message playback should be independent of modem features.
Cannot Upgrade From SM 56 ISA to SM 56 PCI If possible, install the SM 56 PCI modem in a PC that has not had a previous SM 56 modem install. If you have a previous install of our SM 56 ISA modem on your PC you must first un-install that modem completely. A later version of the SM 56 PCI modem software will allow ISA to PCI upgrades. A complete SM 56 ISA modem un-install can be performed as follows: 1. Delete the Motorola SM 56.
inf files from windowsinfother. Delete only SM 56 INF files -- Motorola IncMISGMODM. INF and SERWAVE. INF. 2. From the Windows 95 / 98 Device Manager: Double click Modem, select the SM 56 modem and then click Remove. Optional: If the previously installed SM 56 ISA modem was Data/Fax/Voice double click Sound, Video and Game Controllers, select Wave Device for Voice Modem, and click Remove. 3.
Edit the Windows 95 / 98 Registry (run REGEDIT) and delete the following key: HKLM -- System -- CurrentControlSet -- Services -- SM 3 4 DFV 4. Shut down the computer and remove the SM 56 ISA modem board. Juno is an ISP that provides Web access and enhanced Email services, particularly geared at first time Internet users. When installing these applications they provide a list of "supported" modems and you need to select one from the list.
The SM 56 is not listed. Instead, select Motorola Premier from the list that their install wizard provides. This selection enables the SM 56 to work correctly at full K 56 Flex and V. 90 rates. Super voice is a telephony application that includes data, fax, voice, and Email support. After installation, the application performs a modem initialization sequence. Older versions of the software issue some unsupported AT commands to the modem, which in turn correctly returns ERROR.
On receiving ERROR the application aborts. After working with the vendor, Pacific Image Communications, Inc. , Rev. 2. 2 i 990311 and later of the application functions correctly with the SM 56. Problems with OHCI Compliant USB Devices Freezing When Modem Connected If your PC motherboard uses a USB chip set that is OHCI compliant, (e. g. silicon Integrated Systems (SiS), Opti), there is a chance that a USB device will freeze when the modem is connected. This was found when using a USB camera.
It looks like the USB hub driver freezes up due to the modem hardware interrupts. It usually requires a PC restart to kick the driver back into working condition. This problem does not occur with other USB chip sets that have been tested -- UHCI compliant. It is not a problem with only the SM 56 modem or the software. Other interrupting devices in the PC will result in a similar USB driver problem. Microsoft are working to fix the OS kernel OHCI drivers, and a fix should be included in a a future Windows 98 Service Release. 1) Fixed problem causing OS to blue screen. 1) Changed volume settings for answering machine playback. 2) Added a PCI voice page for speakerphone in the tray app. 2. ) Fixed problem with New Zealand international call progress. 2. ) Moved the tray executable from the run key in the registry to the startup folder.
This fix was required by PC 99 WHQL. 1) Removed Run once key from installation -- required by PC 99 Logo. 2) Implemented call progress through the PC sound system using DirectX 5. 0 and later. 3) Added some fixes to pass Jan -- beep tone and speakerphone levels (used in D/F/Speakerphone only). 4) Install auto-detects country and language settings in the OS and defaults to those. 5) Uninstall now deletes ALL modem components -- including Registry entries and INF files. 6) ATI 8 response customizable via the INF file 7) S 7 (call timeout) now settable 1 - 255. 8) Fixed an array problem in the DSP code which could be encountered when dialing some headend. An overflow could cause OS to blue screen. 9) Fixed fax abort tone mis-detection which could show up under certain circumstances. 1) Cleaned up residual 2400 Hz tone when exiting at ho 12, at ho 13, and at ho 14 commands for countries which use continuous snoop mode for caller id, which occured if caller id was enabled. 2) Cleaned up voice mode connect failure and connect problem when using at ho 12, at ho 13, and at ho 14 commands for countries which use continuous snoop mode for caller id, which occured if caller id was enabled. 3) Added individual DTMF tone level selection per country from 0 to - 15 dBm using the homolog ation utility. 4) Made S 11 register country specific with per country limits settable using the homolog ation utility. 1) Added PCI Plug-n-Play ID for ActionTec. 2) Fixed problem with K 56 flex server not responding to retrain initiated by the remote side during rate negotiation. 3) Fixed power management "wake on ring" bug. 4) Changed the default of the Caller ID alert for Japan from line reversal to short ring. 1) Removed all popup boxes that require user intervention from the SM 56 install program. 2) Fixed a. CAT file location problem with the auto-install feature of the modem. Previous builds require the user to point the install engine to the location containing the original install files. (# 448). 3) Added some V. 34 performance enhancements. 4) Fixed a problem where the modem could disconnect during a V. 90 retrain (either forced gy the user using ATO 1 or by the headend). (# 445) 5) A problem with interrupt sharing on an Intel SE 440 BX- 2 motherboard has been fixed. Previous builds mask off the interrupt line when the modem unloads.
This causes problems for any other device that happened to share that interrupt line. (# 461). 6) Added PCI Plug-n-Play ID's for Window and CIS. 7) Changed all PASCAL and OPTCALL to STDCALL calling conventions. 1) Fixed problem of modem not switching to tone dialing when "D" was encountered in the dial string. This bug was introduced in the previous build. 2) Added country support to the control panel applet. 2) Fixed interoperability problem with Lucent Head ends. 1) The country configuration tables are moved out of memory and into the registry. 2) The Distinctive Ring feature availability is based on registry voice profile key. 3) The product name string in glb ver. h file has been modified to reflect Data, Fax, and Voice capabilities using a single version of that file. 4) Added feature to be able to disallow pulse dialing on a country by country basis. 5) AT#UD command enhancement in DSP. 7) Bug fixes in K 56 fl...
