Character Display Test (Option 21) —
This option generates a continuous output of the alphabet test
message on your async port. The character display test is shown below. This option is also available in
Port Test Mode.
•
Character Echo Test (Option 22) —
The Character Echo Test causes the LinkUp 5294 to echo each
key typed from the keyboard. This includes Attention Keys and Escape (ESC) sequences. Care should
be taken in using this test. Typing other than the displayable ASCII character set (Hex 20 through
Hex 7E) may cause unpredictable results. This option is also available in Port Test Mode. Type
<Enter> twice to return to the options menu.
