Requests and Functions Applicable to SELECT-TEXT State
The following requests are permitted in SELECT-TEXT state. Some
requests have different functions when the line is in other
states. For complete descriptions of the requests, see
Section 3.
• FETCH CONFIGURATION, to retrieve line parameters. You can
find out the values of line parameters, but you can’t change
them in this state. This request does not cause a change of
state.
• FETCH STATISTICS, to retrieve line quality and usage data.
This request does not cause a change of state.
• WRITE data, to send the next message and accept the
acknowledgement. The line state when this request completes
successfully is SELECT-TEXT.
• READ data, to send an EOT sequence and change the state to
CONTROL, then wait to accept a message.
• WRITEREAD data, to send the next message and accept a
conversational reply. The line state when this request
completes with text is READ; the line state when this request
completes with an acknowledgement is SELECT-TEXT.
• CONTROL, to disrupt the WRITE in progress and change the state
to DISCONNECT.
