Telenetics V.32bis Series Registers, AT*RD, Redial Last Number, Display S-Register Value ATSn?

AT*RD, Redial Last Number

Settings: 0, 1 Redial last number one time.

n (The maximum number of redials allowed is country-specific. See the 326X Series Modem Country-Specific Guide for more details).

Format: AT*RDn<CR>

You may redial a failed call n times using the AT*RD command. The modem redials a call until a successful connection is made, or until the call has been attempted n times. The AT*RD command causes the modem to redial the last number dialed. So if an initial call fails, and the telephone number is linked to another number, the modem redials the linked telephone number.

S-Registers

S-registers are memory locations for storing specific configuration and operating parameters. S-registers typically contain timing, counting, ASCII characters, or command option values. While communications software generally insulates you from the need to alter S-register settings, you may want to reconfigure or read the contents of an S-register. This section describes how to read and change S-Register values.

This section is in two parts:

•The first part describes the AT commands used to display and change S-Register values.

•The second part describes S-Registers used by the modem.

Any S-Register that is not stored in memory is reset to its default value when you:

•Power up the modem

•Load a new Option Set

•Reinitialize memory

Displaying and Changing S-Register Values

Display S-Register Value (ATSn?)

Settings: n, Specifies S-Register

Format: ATSn?<CR>

This command displays the value of S-Register n, as stored in volatile memory.

If a “?” appears in the command string anywhere other than immediately following the S-Register number, the command displays the value of the last S-Register selected.

If you try to read the value of an unused S-Register, the modem displays OK.
