Digi Release Notes 93000223_AE for Digi EPC/X, C/X and Xem Async Drivers Digi Xr Async Drivers Digi Xe Async Drivers SCO OpenServer 5.x Software Package P/N 75000154_AE EPC/X, C/X, Xr and Xem Device Driver 7.0.7 EPC/X, Xr and Xem FEP/OS 2.4.3 C/X FEP/OS 3.6.0 Digi Xe Device Driver 7.0.7 FEP/OS 7.08 MPI V4.2.1 Diskette #1 P/N 40001019_AD (3") Diskette #2 P/N 40001383_AD (3") Image file P/N 40001803_AE Source file P/N 81000024_AE August 8, 2006 This Digi software package includes device drivers for the Digi Xe, Digi Xr, EPC/X, C/X and Xem product families. This package also contains Digi's MenuPort Interface (MPI), Port Configuration Utility (PCU), and Digi Port Authority (DPA). MPI V4.2.1: 1. Enhancements Worked around a problem with new Intel Motherboards. These motherboards do not support PCI BIOS32 calls anymore. The driver now uses a different method to detect its cards. 2. Bug Fixes None 3. Known Limitations If multiple Xr(PCI) cards are being configured, and the cards support different numbers of ports, make sure the card placement on the PCI bus match the order in which they are configured in MPI. The PCU program is provided "as is". Under very rare circumstances, the PCU program will get too confused to correctly set up the ports. In this situation, you will need to manually configure the serial ports within the host O.S. If you get errors on boot that say "Another Process Waiting on Open", you can put the command "sleep 10" as the first line in "/etc/rc.d/8/pcuepca" which will delay the execution of the ditty commands until the download process has a chance to complete. The device driver update function from MPI v2.0.1 or earlier may not work properly with later versions of MPI. For maximum performance of throughput, all of the concentrators should be evenly divided between the 2 lines. Canonical input ttyhog processing works slightly different than might be expected. If the UNIX input highwater mark is reached without the eol character being received, echoing stops until the board's input buffer overflows or an interrupt character or break is received. Scancode terminals, under VP/ix, must be configured for 8 databits, 1 stop bit, and no parity as scancodes are 8 bits wide. 4. Manual Errata None 5. History MPI V4.2.0: - Removed AccelePort RAS support. - Added changes so the package is compatible with the new software package dgap that will now support all AccelePort RAS, DataFire RAS and AccelePort Xp adapters. - Corrected a lock timeout panic condition that occurs on SMP systems. - Fixed ditty so that it can be used by a non-root user without getting errors printed out on the console. MPI 4.0.0 - Added AccelePort RAS support.
