Performing a Direct Operating System Download

Operating System Downloads
The procedure described in Table 23 below explains how to download
a complete version of the TXO operating system from a download
computer to an Omni 3200 terminal over a serial cable connection.
In Table 23, you will note that the first step of an operating system
download procedure is different than for an application download.
Specifically, you must disconnect the power supply from the terminal,
and then reconnect the power pin while holding down the [CLEAR]
key. This causes the terminal to enter a special mode, indicated by a
dual-tone beep, in which the bootloader software is running and the
operating system is stopped.
To enter this terminal mode, in which only the bootloader is running,
you must key in a System Password, regardless of whether or not an
application has previously been downloaded into the terminal
memory.
Note: An operating system download procedure overwrites the
application program and all CONFIG.SYS records, protected and
non-protected, on the receiving terminal. Please read the introductory
information in this section carefully before you start!
