REQUESTS AND FUNCTIONS APPLICABLE TO READ STATE. The following
requests are permitted in READ 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 aren't |
| allowed to 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. |
| |
| |
| READ DATA, to acknowledge the last message and read the |
| next one. The line state when this request completes |
| successfully is READ. |
| |
| |
| WRITEREAD DATA, to make a conversational reply, and accept |
| an acknowledgement or conversational reply. The line state |
| when this request completes with text is READ; the line |
| state when this request completes with an acknowledgement |
| is WRITE. |
| |
| |
| CONTROL, to disrupt the read in progress and change the |
| state to DISCONNECTED, or to send a WACK reply to a |
| message. If you use this request to send a WACK, the |
| line state upon completion is READ. |
| |
| |
| SETMODE, to change the retry count or the block length |
| for transparent text. This request does not cause a |
| change of state. |
| |
| |
| ABORT, to stop a request in progress, for example, a READ |
| request. The line remains in the state in which the work |
| was interrupted. |
