Echo
Option Values: on, off
Applicable Data Protocols: All
This option determines whether characters sent from the data terminal in Data Mode are echoed
by the ADM.
If you select on, the ADM echos characters sent by your data terminal during Data Mode.
Select on if your host computer or other data endpoint does not echo characters. In addition,
you will want to turn your data terminal's echo capability off.
If you select off, the ADM does not echo characters sent during the Data Mode. Thus, if your
host computer or other data endpoint echoes characters for you, select off. Otherwise, each
character you type is displayed twice. If you are transferring files, you will probably want to
turn Echo off.
Edit
Option Values: on, off
Applicable Data Protocols: X.25, Mode 3, BV64I, and BV56I
This option is used with the Forwarding option and allows you to correct characters and lines of
text before transmitting data packets to the far end. If you type more than a full packet of data,
then a packet is sent out automatically.
Select on if you want to be able to edit packets before you send them; select off otherwise. Note
that Forwarding must not be set off for Edit to work.
The characters that you can use for editing are selected with the Char.erase and Line.erase
options. These characters are acted on locally and are not sent out in packets.
Interactions with Char.erase and Line.erase: At least one of these options must be set to a
value other than off for editing to work.
