This document describes the Lantronix CoBox Device Server firmware release. =============== RELEASE SUMMARY =============== Current release: V4.5 ============================= ADDITIONAL PRODUCTS SUPPORTED ============================= V4.5 supports the CoBox Mini, CoBox Mini100, and CoBox-FL, as well as the CoBox Micro, UDS-10B, DR1, UDS-10, and CoBox-E2 products. ================= FIRMWARE RELEASES ================= CBXnnn.rom: Supports old HW platforms, without encryption. LTXnnn.rom: Supports all of the new HW platforms without encryption. LTXEnnn.rom: Supports all of the new HW platforms with encryption. ============ NEW FEATURES ============ 1. Setup mode -Added a warning for when the user sets 2 stopbits in AMD-HW. The warning works only in serial and telnet setup, not in WebManager. The warning is displayed as the following: ATTENTION ! This hardware does not support 2 stopbits ! -Added an Expert Settings menu option in the main menu of devices running LTXnnn.rom, or LTXEnnn.rom. -Added a TCP Keep-alive Timer setting under Expert Settings. The range is...(1s - 65s; default = 45s; 0s=disabled). -Added the ability to change the SNMP community name in Security settings. -In the Security options, you now have the ability to disable SNMP. 2. AT Commands -Added 1 character response in Modem Emulation. The Connect mode for 1 character response is 0x07 (X7). The connect mode for full verbose is 0x06 (X6. This version of firmware has additional support of the following AT commands: -ATS0=n enables or disables connections from the network going to the serial port. -n=0 disables the ability for a connection made from the network going to the serial port. -n=1 through 9 enables the ability for a connection made from the network going to the serial port. -n>9 is invalid. -ATEn enables or disables character echo and responses. -a)n=0 disables character echo and responses. -n=1 enables character echo and responses. -ATVn enables 1 character response or full verbose. -n=0 enables 1 character response. -n=1 enables full verbose. These AT commands are only recognized as single commands like ATE0 or ATV1; commands such as ATE0V1 are not recognized. 3. Other enhancements -Added support for the new 91c110 chip (mini100). -Added a sequential hostlist to the LTXnnn.rom and LTXEnnn.rom versions of the firmware. A sequential hostlist does not make a connection to all IPs in the hostlist table at one time. The way the hostlist works is to scroll through the hostlist until the Lantronix product makes a connection to a device listed in the hostlist table. Once it makes this connection, it stops trying to connect to any others. If this connection fails, the Lantronix product continues to scroll through the table until it is able to make a connection to another IP in the hostlist. The way you use this ability is described below: 1. The hostlist is enabled by using a connect mode of 0x20 (2X). 2. The menu shows you a list of the current entries already defined in the product. 3. Now you will be asked if you want to change the hostlist. If you want to delete, modify, or add an entry, choose yes. If you enter an IP address of 0.0.0.0, that entry and all others after it are deleted. 4. After completing the hostlist, you get the option to edit the hostlist again. Repeat the previous step if necessary. 5. The next option is the hostlist Retrycounter. This option is used when the Lantronix product successfully ARP's a hostlist entry, but can not make a good network connection to that entry. The Lantronix device tries to make a connection the number of times set in the Retrycounter. 6. Next the Retrytimeout displays. The Lantronix product waits this long before failing an attempted connection. ============== FIXED PROBLEMS =============== 1. DHCP -Finished DHCP rework. -DHCP option 61 now shows MAC address instead of Cxxxxxx; Cxxxxxx caused trouble in windows DHCP servers. -DHCP now accepts broadcast as an answer for DHCP requests. 2. 'C' message -If the Response bit in the connect mode was set, the 'C' message could have been sent too late (in the middle of data). Now, the 'C' message is always sent out before data. 3. Other corrections -Assigning the IP address via the ARP command now works with all gateway/netmask settings. In the past, situations occurred in which the command did not work. -Send characters now works for port 2 properly. In the past, port 2 used the send character settings from port one (ignoring the settings for port 2). -0d 00 is no longer converted to 0d when using the redirector. -Port 2 on a CoBox-E2 now works. Port 2 did not work in firmware 4.4. -Fixed all serial driver problems for CoBox-E2 and CoBox-FL. -The Lantronix product no longer reboots when you choose option 8, "Exit without save". -Fixed MS-Windows problem of 5s delay with small TCP window size. -This version of firmware correctly handles incoming break bursts. These break bursts were caused by leaving the TX and RX pins of an embedded Lantronix device unconnected. -Changed some Setup text. ========= BUG FIXES ========= -This version of firmware works with BOOTP. Version 4.4 did not. -The SNMP OID SysObjectId now displays properly. In version 4.4, this OID displayed as garbage. -The modem command ATD now works the same as ATDT. In previous versions, ATD did not have the full functionality of ATDT. -Fixed an ARP bug that occurred when the hostlist functionality was enabled. -Fixed a bug in the I2C routine that may have effected flow control when storing data in the I2C EEprom. -Fixed the monitor mode command GC n.n.n.n. The command had not worked since Release 4.3. -Fixed the monitor mode commands GC and SC for old HW platforms with little EEprom (128 byte). This command just returned an error >9 in firmware version 4.4. -Fixed a bug causing data loss at a speed of 38400 in the Mini Rev1 while using software flow control (Xon/Xoff).
