Release Notes PN 93000459_L Digi One SP and Digi One IA EOS 82000774_G June 17, 2005 INTRODUCTION This is a production release of firmware for the Digi One SP and Digi One IA. These devices provide high-performance serial port connectivity with added EIA-232/422/485 switch selectable support on the serial port. These devices come with RFC-2217 support, TCP Server (Reverse telnet/raw), Autoconnect (TCP Client), UDP Serial Client/Server, ARP-ping, Advanced Device Discovery Protocol, and Digi's patented RealPort protocol for COM port control. SUPPORTED PRODUCTS Digi One SP Digi One SP Secure Digi One IA IMPORTANT UPGRADE INFORMATION - Before upgrading the 82000774 firmware, it is necessary that you have a POST firmware that supports the current revision of the 82000774 firmware. Failure to have a compatible POST will result in the device becoming unusable. - To determine the current version of POST firmware using the WEB interface go to the Administration/"Update Firmware" page. The "Update Firmware" page should display the current POST version and should look something like: POST: release_82000775_F - To determine the current version of POST firmware using the command line interface, type "show versions" at the command prompt. - If the POST version is 82000775 revision A through E you must upgrade to the POST version 82000775_F or later. - If the POST version is 82001178 nothing needs to be done. ENHANCEMENTS - Port sharing feature added. - Modbus protocol added (activated on Digi One IA only). BUG FIXES - Fixed a problem where the device was not routing supernet type routes correctly. - Fixed a problem where our device was failing to properly negotiate RFC2217 options. - Fixed a problem with auto connect telnet and auto connect rlogin where escape characters would cause the connection to escape to the command line prompt. - Fixed a problem where it was not possible to disable escape characters for telnet, rlogin, and connect sessions. - Fixed a problem where rapidly opening and closing serial socket connections was causing a serial port to get stuck. - Fixed a problem where auto connections configured with raw IP addresses were slow to connect when a bad DNS server was configured. - Fixed a problem where auto connect was sometimes losing data if large amounts of data was being sent while the network connection was being established. - Fixed a problem where a raw auto connection was failing to establish a network connection when the data byte 0x03 was being sent during connection establishment. - Fixed a problem with the auto connect flush character option. This option was causing more than a single byte of data to be flushed. Furthermore the default setting for raw connections and connections when the serial device type was not term was incorrectly flushing data. - Fixed a problem where an error message was being returned when using the "set user" command to configure an auto connection with a DNS destination address. - Fixed various UDP serial problems. KNOWN LIMITATIONS - In order to run a firmware that is 82000774_G or greater it is necessary to have POST firmware that has the partnumber 82001178 or the POST firmware that has the partnumber_revision that is 82000775_F or greater. To determine the version of POST that is being run, using the WEB UI go to the "Administration"/"Update Firmware" page, or using the command line enter the "show version" command. ADDITIONAL INFORMATION - not applicable HISTORY April 6, 2005: 82000774_F4 BUG FIXES - Fixed problem that occurs when running on newer devices that contain the 82001178 POST. The WEB UI would not allow reboots to occur. 2004-11-19: 82000774_F3 BUG FIXES - Insure that Digi One IA CR is properly reported via ADDP 2004-11-12: 82000774_F2 BUG FIXES - The Digi One SP device will reset the flow control to hardware when power cycled - When configured for "Always connect" it will not connect when placed in 422/485 mode. - Setting the IP address through ADDP and rebooting the device may result in the IP address not being saved to NVRAM - UDP 2773 Debug port open when not in use - Rlogin fails to make a proper auto connection from a serial port - rlogin esc character not working - The 'show versions' command cuts off the last character. - Help for CLI in Digi One SP/IA firmware states incorrect base socket values - Keepalive disconnects a connected session where no traffic has passed 2004-09-17: 82000774_F1 ENHANCEMENTS - Enahced the PMODEM ati3 response to include firmware version BUG FIXES - Resolved an issue where the same IP can be assigned to two different devices via DHCP - Allow host names that start with a number in the Web UI - Resolved an issue where TCP socket 2101 refuses connections 2003-10-30: 82000774_F - Allow HTTP Web UI port to be changed from the default of 80 2003-06-06: 82000774_E ENHANCEMENTS - Command line interface support - DHCP Keepalive - Web user interface port profiles - by default the profile will be custom. It is recommended that the correct profile for your envrionment be selected. This can be done through the wizard (version 1.2 or higher) on the CD, or through the web interface. The new profiles quicken installation process by only enabling applicable parameters for optimal operation. - Base socket configurable with any integer between 1999 to 50000 2003-1-23: 82000774_D - New web user interface - Send serial buffer after timeout 2002-12-16: 82000774_C - Digi RealPort Protocol Support - Latency Options and Enhancements - Settable Ethernet Speed and Duplex - TCP Keepalive Options and Enhancements - Ability to Kill Connections (Who) - Copy Configuration (CpConf) 2002-09-06: 82000774_B1 - Minor, internally-found bug fixes. 2002-08-07: 82000459_B - Support for SP hardware. 2002-06-01: 93000459_A - Initial release of firmware for DigiOne IA. 2002-06-18: 82000774_01 - Beta Release of firmware.
