2.9.2 Editing the Device Table
The device table is a list of devices catagorized by family name and device first
name. The software diskette provides a device table file, device.tbl, that con-
tains a list of devices and their configuration parameters. The devices and their
configurations are loaded automatically when the programmer software is in-
voked.
Pressing from the port # field causes the cursor to enter the device table
field. When this occurs, several function keys and their actions are displayed
at the bottom of the screen. (Choosing
edit from the command line will also
place the cursor directly into the device table field if this field is the last one you
worked in. In other words, the
edit command defaults to the last field you were
in before exiting back to the command line.)To edit the device table, use the
commands listed in Table 2–4.
