AT\O Initiate MNP
The modems initiate reliable mode from normal mode. Then the modems
send two reliable link sequences. If the modem does not respond after
20 secs. the data connection remains as it was before. If the remote
modem accepts the request the current connection is displayed with a
CONNECTxxx report.
This command is only applicable during in command mode after the
ESCAPE sequence. It refers to the subsequent establishment of a MNP
connection using the AT\U command.
AT\Y Initiate MNP Error Correction
The command is utilized to request an MNP connection from command
mode whichis normally not valid for MNP operation. First transmit a
ESCAPE sequence (+++) and then the command AT\Y. The modem
operating in originate mode now begins to initiate an error protected
connection (reliable link) to the remote modem. The remote modem which
is in answer mode waits max. 9 secs. for the establishment of a reliable
link (supposed AT/C1 or AT/C3 is selceted). If the establisment of a reliable
link is not possible after the second attempt the modems remains in a
non MNP connection.
AT\Z Deactivate MNP Error Correction
The modems switch during the ESCAPE state of an MNP connection
from reliable to normal mode.
The contents of the buffer is being erased.
