Editing the Configuration Parameters and Device Table
2.9.2Editing 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.
