Setting Up the Download Computer (ZONTALK)
You must set up three files on the download computer before
performing a ZONTALK operating system download by telephone:
<terminal>.FAM, <terminal>.TMS, and <terminal>.TDD:
• <terminal>.FAM — The Family Type file for the download must
contain an entry such as:
OMNI-OPSYS nn, X6
where ‘nn’ is a two-digit number identifying the family type in
the ZONTALK log file. You can select any unique value.
• <terminal>.TMS — The TMS file must contain an entry such as:
OMNI*, * = internal 5
• <terminal>.TDD — The Terminal Data Directory file for the
download must contain an entry such as:
OMNI-OPSYS Appl_ID Filespec
where ‘Appl_ID’ is the operating system name, and ‘Filespec’ is
the (path\) filename that ZONTALK will use to locate the
Terminal Data Records.
You can use a modem download file, <Appl_ID>.DLD, to define
the operating system binary file that is sent to the requesting
terminal. This way, the terminal does not have to “know” the new
operating system name prior to requesting an operating system
download. The .DLD download file may contain such entries as:
[KEY] [keyvalue1] 4 Opsys1.bin
[KEY] [keyvalue2] 4 Opsys2.bin
where ‘KEY’ (keyword) and ‘keyvalue’, when set appropriately
in the ZONTALK Terminal Data Records, let you selectively
download different operating system binary files according to
their corresponding KEY values.
