Enhanced Signal to Noise Ratio for Analog Modulations. Improved debugging capabilities (CSC logging). BUG FIXES This release includes all bug fixes from any previous version of driver software release for the supported adapters. For DataFire RAS adapters, firmware was updated to include the following fixes: Wink and immediate start signalling fixes. Class 2 Fax fixes for RAS 4 Management statistics reporting fixes. CSC lockup fixes. Fax and modulation fixes. V.110 PPP mode fixes. KNOWN LIMITATIONS Operating System Support: This release no longer supports Windows NT 3.XX. Installation/User Interface: Within the wizard mode, if invalid input has been entered and back button is pressed, an error message may appear indicating that the input is invalid. A valid input needs to be entered to be able to go back. PortAssist Viewer: The PortAssist Viewer shows a Line Speed and Configured Baud Rate of zero for the SYNC/570 if the link is externally clocked. If the link is internally clocked both values show the Configured Baud Rate. The SYNC/570 does not calculate the Line Speed. PortAssist Viewer will show a protocol of SDLC for QLLC SNA links. Use the raw data for problem diagnosis. RAS Adapters: On Channelized T1 Wink Start Trunks without dial tone supervision, modems must be initialized with ATX3 for dial out. When configuring dial up modem service for a line, all modems on the line should be configured since incoming calls may be assigned to any channel. On ISDN Trunks, the following rules are applied to modem dial strings: a) A comma (delay) in the first or second position is allowed. b) then the first non-numeric character terminates the dial string (e.g. 9,12345678 is a valid dial string and 9,1,234-5678 is not). UPGRADING If you have a previous version of the driver installed for any supported adapters, an "update" is required to install this new driver. 1. Select the Network Control Panel Applet. 2. Select the Adapter tab. 3. Select one of the supported installed adapters. Note: updating any supported adapter automatically updates all installed adapters. 4. Click the Update button. 5. Enter the appropriate install directory (e.g. D:\i368 for Intel) HISTORY Version 3.6 ENHANCEMENTS DigiView trace feature now decodes several more ISDN Information Elements: Maintenance/Service Messages, Call identity, Restart indicator, Display text, Change status. BUG FIXES This release includes all bug fixes from any previous version of driver software release for the supported adapters. DigiView trace feature sometimes identified ISDN SETUP packets as UI frames on Basic Rate ISDN (BRI) lines. A problem was fixed where service messages brought down the PRI line on some National ISDN switches. Problems relating to the failure to establish ISDN modem connections were fixed. A problem where B channels were not being hung up correctly was fixed. A problem was fixed where no B channel status information was being reported for higher numbered B channels. A problem was fixed for the DataFire RAS 48 adapter where status information on line 1 was being misinterpreted as status information for line 2. Finally there was a bug that was fixed that might have potentially caused problems with adapters that have interrupts activated. No such problems have been reported to date. Version 3.5 ENHANCEMENTS CompactPCI Adapter Support. New SYNC 2000 V.11 and V.35 Cable ID recognition. Improved performance for Frame Relay, X.25 and FRF.9 compression. Support for Cisco proprietary encapsulation of IP over Frame Relay. Cisco routers have multiple encapsulation schemes for IP on Frame Relay, this mode is the default. Improved modem support for RAS products. V.23 half-duplex mode can now be set and used via AT+MS=4 BUG FIXES Modem support maintenance fixes for RAS products. Fixed bugs in operation of the AT command set Fixed bugs in the generation of digital messages that contain capability information (such as negotiating positions in FAX and v.8bis. Fixed bugs in the generation of digital FAX image data. Several fixes to ISDN data handling. Some fixes for management informational ioctls. Version 3.4 ENHANCEMENTS PPP protocol support for the Sync570 adapters. Support for IBM Comm Server NT v6.0 for the Sync570 adapters. Alpha processor support for all supported adapters. Windows NT 3.51 support for DataFire RAS and AccelePort RAS adapters. PortAssist Communication Agent service is installed providing communication with PortAssist Manager. This agent uses UDP port 2362 by default, but may be configured for a different port on the Services tab of the Network Control Panel. BUG FIXES This release included all bug fixes from any previous version of driver software release for the supported adapters. Various minor user interface bugs fixed.
