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, 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.

FCPN (Flow Control Parameter Negotiation)

Option Values: off, on

Applicable Data Protocols: X.25

A FCPN selection of off is used to enable the default values of the window size and the

maximum packet size (2 and 128, respectively) by directing the ADM not to request the X.25

Flow Control Parameter Negotiation facility.

A FCPN selection of on is used to request a window size of 3 and a maximum packet size of 256

in the X.25 Flow Control Parameter negotiation facility. Check with your system administrator

to find out if on is a selection that is available to you.

If this option is changed during an active data call, it does not take effect until the next data call.

Note: A FCPN setting of off is recommended when more than four ISDN terminals connected

to the same line are simultaneously using DX25 packet data communication.

Otherwise, under worst case load, packet congestion on the line may result in lost data.
