(Note: User input is preceeded by ">" character at the beginning of a line. The ">" is not part of the user input, it is just used as a marker to clarify the following instructions.) Loading a new firmware version: Instead of copying the new firmware version NNN to a PCMCIA card and loading it as described in the user manual on page 41, you may alternatively copy the file mlsNNN.mls to the current subdirectory and load it as follows using the SENDCOM program (NNN stands for the current version number): At first, the old firmware version has to be erased: > ?forth empty-erom boot now the MLS comes back with its ROM sign-on message > include mlsNNN.mls starts the firmware loading process. The messages displayed are identical to the ones you see when you load via the PCMCIA card. Eventually, the system will boot displaying e.g. the following messages: GEOLON-MLS SN_000712 ROM_1.46 08.11.2000 (c) SEND GmbH MLS-FW Version 1.24 14.11.2000 (c) SEND GmbH boot unsynchronized -------------------------------------------------------------------------------- Loading a new operating system (ROM) version: Every now and then, changes have to be made to the operating system itself. If you intend to load a firmware version which requires a newer operating system version, the firmware loading process will be aborted and the message "incompatible ROM version" will be displayed. Now you should load the latest ROM-version. romNNN.mls has to be copied to a subdirectory (NNN stands for the current version number). Then SENDCOM has been started in this subdirectory. At first, the currently loaded firmware-version has to be erased with the following command line: > ?forth empty-erom boot now the MLS comes back with its ROM sign-on message > include romNNN.mls starts the ROM update, printing numbers from 0 .. 70. The whole process takes some minutes. This is a example screenshot of the loading process: beginning screenshot ----------------------------------------------------------- include rom146.mls 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 MLS-loader v1.02 (c) 1999 SEND GmbH DEVICE ID IS: $000422BA CALCULATING CRC-CHECKSUM...

Then you can proceed loading the new firmware version using > include mlsNNN.mls and everything proceeds as described above. Finis
