The remainder of this chapter describes each off-line function key.
Function
The ON LINE key selects either the on-line or the off-line mode of operation for
the universal programmer. (Each time the ON LINE key is pressed, the universal
programmer switches from one mode to the other.) After pressing the ON LINE
key to enter on-line mode, the following message is displayed in the command
field of the iUP-201 A alphanumeric display:

When in on-line mode, all iUP-201A keys are disabled (with the exception of the
ON LINE key).
Pressing the ON LINE key again switches the universal programmer to off-line
mode and causes the following message to be displayed:

The remaining keys described in this chapter operate only when
the universal programmer is in off-line mode.
