Diagnostic Commands

Using remote diagnostics, a technician or programmer working from
a diagnostic computer can exchange information with an Omni 3200
terminal. This exchange can be direct, using a serial cable connection,
or it can be done over a telephone line using a modem.
The Omni 3200 terminal's remote diagnostics capabilities permit the
use of highly automated test procedures with a minimum of user
intervention at the terminal.
The only task required on the terminal side of the diagnostics session
is to enter System Mode and initiate a simple procedure. The
procedure for conducting a remote diagnostics session varies slightly,
depending on whether remote diagnostics are to be performed
remotely over a telephone line connection or on-site using a direct
cable connection.
The diagnostic computer can send the following commands to the
terminal. These same commands are also used by the terminal's
debugging feature. Detailed descriptions and formats of these
commands are provided at the end of this section.
