Use this command to store a dialing string. Controller-based modems can save four dialing sting. The
format for the command is &Z<storage_location> = <dialing_string>. The dial string may contain up to
40 characters. The ATDS=<storage_location> command (D<dial_string>—Dial on page 13) dials using
the stored string.

ERROR if <value> ≠ 0—2.
•
\A<value>—Select Maximum MNP Block Size
Use this command to select a MNP error corrected link with a maximum block size controlled by the

\B<break_time>—Send Break
Use this command in non-error-controlled mode. The command causes the modem to transmit a break
signal to the remote modem. The minimum break length is 100 ms, and the maximum break length is 900
ms. The <break_time> parameter has values between one and nine, with each increment representing
100 ms. The default of <value> = 3 corresponds to a length of 300 ms.
The command works in conjunction with the \K (\K<value>—Set Break Control on page 30) command.
Result codes:
• OK if connected in data modem mode.
• NO CARRIER if not connected or if connected in FAX modem mode.
ERROR if <break_time> ≠ 1—9.
•
\G<value>—Modem Port Flow Control
Use this command to process XON/XOFF flow control locally or pass XON/OFF flow control to the remote
