Description

The answerback data string may consist of from 0 to 30, 7- or 8-bit characters, which are hex pairs in the range 3/0 - 3/9 (0 through 9), 4/1 - 4/6 (A through F), and 6/1 - 6/6 (A through F).

Once defined, the message may be stored in the non-volatile memory if Save settings is executed in the Set-Up.

The selective parameter denotes the encoding of the answerback message. A "1" is always used for the VT510 indicating answerback is encoded as hex pairs. The sequence is ignored if any number other than "1" is specified in the Ps field.

Pressing Ctrl/Break or receiving ENQ code causes the VT510 to transmit the answerback message. In on-line mode, the answerback message is transmitted to the appropriate host port. The answerback is not echoed in local echo and is not "sent" in local mode.

The answerback message is transmitted as keyboard data. Any speed restrictions (as set in limited transmit) apply.
