Release Notes 93000329_3P for Digi DataFire/AccelePort RAS UnixWare 7 Package Release 1.0c Release Date 04-16-99 Please reference the following number(s) when searching the Digi International FTP/WWW site for the latest software package: Package Image P/N 40001891_3P These numbers are for informational purposes only: DataFire CD-ROM Package Image P/N 40001892_3P AccelePort CD-ROM Package Image P/N 40001893_3P Source P/N 81000097_3P This Digi software package includes device drivers for the AccelePort/DataFire RAS products supported under UnixWare 7.0.1 and above. This release includes support for multiple Host Adapters per system. The following Host Adapters are supported on this release: All Digi AccelePort RAS adapters and All Digi DataFire RAS adapters Software limitations: * The maximum number of Acceleport RAS and DataFire RAS cards combined in one system is currently set to 7. * Async ports are configurable through the serial and modem managers. The system must be at revision 7.0.1 with ptf7053b applied in order for the serial manager to operate properly. Additional Notes: * Only the first line of a multi line adapter will show up in netcfg until the first line is configured. * When configuring a mult-line adapter, the lines must be removed in the opposite order in which they were installed. * For AccelePort RAS adapters, you will get the following messages that are informational only and do not affect the operation of the adapter or the protocol stack. NOTE: dgisdn: Open to non-ISDN device (/dev/mdi/dgisdn) dlpid: Unable to open network adapter driver (/dev/mdi/dgisdn) dlpid: No such file or directory Known Problems: * If you get an "net on /dev/mdi/dgisdn is inopererable" message during re-boot, it is due to netcfg limitations for configuring Digi Multi-Line ISDN adapters. On a Multi- Line adapter (a two-line T1 or E1 or a four-line BRI adapter), netcfg is able automatically to detect only the first line. Once the first line has been configured, Digi scripts make the subsequent lines visible to netcfg for configuration. Because of the resmgr and netcfg limitiations, it is ABSOLUTELY NECCESSARY that ALL Digi DataFire/AccelePort RAS adapters have their first/only line configured via netcfg BEFORE ANY second, third or fourth lines on a multi-line adapter are configured. If a additional Digi DataFire/ AccelePort adapter is to be added to a system that already has a configured multi-line adapter, ALL Line TWO, THREE and FOUR configurations must be removed via netcfg prior to inserting the new adapter. After the new adapter has been configured via netcfg, all of the line two, three and four configurations can be re-done via netcfg. * When configuring adapters, you must choose the correct adapter type in netcfg until it is capable of properly detecting the adapter type. * There is a creeping instance number problem that causes device names to change if removing and adding with netcfg without rebooting the system in between. If removing an adapter through netcfg, reboot the system before adding the adapter back into the system. * When removing the last configured dgisdn adapter via netcfg, the following messages are displayed on the console. There is no obious problem related to this error message, everything seems to work correctly. dlpid: StopInterface: Unable to find DLPI interface (net) in internal table dlpid: RemoveInterface: Unable to find DLPI Interface (net) in internal table * There is a bug in UnixWare 7.0.1 that causes kernel panics when disconnecting from a digiras async port. The patch ptf7096d will correct this problem. It can be found at ftp://ftp.sco.com/SLS or ftp://ftp.dgii.com/support/drivers/unix_svr4/released/async * The netcfg program may abort if there are third party devices in /etc/uucp/Devices. Until a fix is provided by SCO for this problem, you must remove the third party devices from /etc/uucp/Devices before running netcfg. * After removing an adapter from NETCFG, the O.S. must be rebooted to complete the adapter's removal process. The networks will still be operational until after the reboot. * As of the date of this release, the serial manager will only set up ports for PPP with the flags 'oP'. If you want to run a standard login shell, execute the command /usr/local/bin/fixmon after the port is configured through the serial manager. This program will allow you to set or clear the 'oP' flags. If the 'oP' flags are set, the ttymon will not attach to the port (open it), and you will never get the modem to answer. * The modems associated with async ports supported by this driver are auto detectable through 'scoadmin modem'. You can modify the dialer script '/etc/uucp/default/RAS_modem_56000' to customize your initialization strings. * The program '/usr/local/bin/rasmon' can be run to monitor configured ISDN and async devices supported by this driver. * In earlier releases of UnixWare 7.x.x, PPP configuration of ISDN lines through netcfg assumes BRI, causing only two B-channel links to be defined. To define the rest of the B-channel links and make them available for PPP configuration, you must define them via ppptalk. For ISDN PRI lines over T1, you can define up to 21 additional B-channel links and for ISDN PRI lines over E1, you can define up to 28 additional B-channel links. Note that before using ppptalk to add the additional B-channel links to your ISDN PRI PPP bundle, you must have first configured it via netcfg. To add links via ppptalk, type "ppptalk list bundle ". Choose one of the links listed in "links = link_". Then type "ppptalk copy link link_ ", once for each additional B-channel link you wish to add to the bundle. Note that must be unique for each link, but the same link_ can be used for all of the commands. When all of the desired links have been added type "ppptalk bundle links=old_link_1 old_link_2 new_link_name1 ..., INCLUDING ALL of the links in the bundle, old and new. You may wish to adjust minlinks and maxlinks at this time with "ppptalk bundle minlinks=x" and "ppptalk bundle maxlinks=y". At this point your changes are permanent but will take effect only at the next re-boot. To have them take effect immediately, you must type "ppptalk reset bundle ". This causes and all of its links to be reset. A copy of these release notes can be found in: /etc/inst/nd/mdi/dgisdn/rnotes
