198 Chapter 5 Working with Formats
Creating custom formats using the command line interface
There are two methods for creating formats through the command line interface. The first
method is to use the FMTN command to set all format parameters in the format buffer to
their default values, and then modify each value. The second method is to select an
existing format to use as a template for the new format, and then modify only the values
needed to create the new format. When using this method, you can save the new format
under a new name or the existing name.
Independent of the method you choose, you can enter each command interactively or
create a text file containing all the commands you want to issue, and then download the
text file to the generator. See “ Configuring the 882’s serial port ” on page 30 for more
information about sending commands to a generator.
The FMTN command is used in creating a new format. This command sets all of the
format parameters to known, default values. For a list of the parameters and their default
values, see “ FMTN ” on page 344. Use the following procedure to create a new format
using interactive commands.
To create a new format using the command line interface:
1. Establish a session with the generator using HyperTerminal over a serial connection or
Telnet over an Ethernet LAN. For instructions, see “ Establishing a terminal session with
the 882 ” on page 30 and “ Establishing a Telnet session with the 882 ” on page 33.
2. Set the format path to the medium where you want the new format stored using the
following command:
FMTP /tffs0/Library/Formats // sets format path to flashmem directory
3. Enter the following commands to initialize all parameters to default values and begin a
format editing session:
FMTN // initializes all parameters to default values
FMTB // begins a format editing session
4. Enter the format parameter commands in sequence to set the values for the new
format.
HRES 654 // sets the horizontal resolution to 654 pixels
.
. // other format parameters
.
HTOT 720 // sets the horizontal total to 720 pixels
Note: You do not need to enter a parameter value if it matches the FMTN default
setting. You can query a parameter to determine its current value.
5. End the editing session and save the new format using the following commands:
FMTE // ends a format editing session
FMTA new_fmt_name // saves format as new specified name
