Data Options and Profiles

Local.erase

Option Values: Any ASCII character except NUL, SOH,

Ctrl

, (default = BS)

Applicable Data Protocols: N/A

This option selects the character used to backspace (erase) a Local Mode

command character. Some PC communications packages access this option

from the AT Local Mode. Individual users should not change this option value.

Unlike most data options, Local.erase is an unstored option (it is not stored in a

programmable profile), and its setting reverts to the factory default value upon

power-up.

Local.lf

Option Values: Any ASCII character except NUL, SOH,

Ctrl

, or BS (default = LF)

Applicable Data Protocols: N/A

This option selects the character used as a linefeed during transmission of

responses to Local Mode commands or when Local Mode commands are

echoed. Some PC communications packages access this option from the AT

Local Mode. Individual users should not change this option value.

Unlike most data options, Local.lf is an unstored option (it is not stored in a

programmable profile), and its setting reverts to the factory default value upon

power-up.

Match.speed

Option Values: on, off

Applicable Data Protocols: Mode 2

This option permits endpoints running at different speeds to communicate via the

Mode 2 protocol. To establish a Mode 2 data call both endpoints must be at the

same speed or the Match.speed option must be on at the endpoint with the

higher speed.

The terminal adaptor connected to the higher-speed endpoint buffers up the data

and meters it toward the network at the rate of the lower-speed endpoint, and

controls the data flow from the attached equipment using the Trans.flow control

mechanism. If Trans.flow is off or if the attached terminal does not support Flow

Control, you are likely to lose data. Mode 2 protocol does not provide an end-to-

end flow control mechanism for connection of endpoints with mismatched

speeds. The lower speed endpoint must not send xon/xoff characters to control

the flow of the high speed endpoint because these flow control characters

become mixed with any xon/xoff characters sent to the higher speed endpoint

generated locally by the higher speed ADM. If this condition occurs, data will be

lost because two independent entities (the local
