33.4.5 +iRDL — Number of Times to Redial ISP<br />

Syntax: <strong>AT+i</strong>RDL=n<br />

Sets the number of times to redial ISP.<br />

Nonvolatile Parameter Database<br />

Parameters: n= Number of redial attempts to the ISP. If the ISP number<br />

is busy or the ISP does not pick up the line, the system will<br />

attempt to redial the ISP after a delay period as defined in<br />

the RTO parameter. If all redial attempts are exhausted, an<br />

attempt to dial the alternate ISP number will be made, if an<br />

alternate number exists. In the event that the number is<br />

busy or the ISP does not respond, the system will attempt<br />

to redial up to n times, as with the primary ISP number. If<br />

all redial attempts are exhausted, the system will quit with<br />

the error message: ―All Redial Attempts Failed.‖<br />

Command Options: n=0 .. 20<br />

Default: n=5<br />

Result Code:<br />

If the ISP does not pick-up the line, the iChip will timeout<br />

and determine a redial situation after the number of<br />

seconds stored in the WTC iChip parameter.<br />

I/OK If n is within limits<br />

I/ERROR Otherwise<br />

<strong>AT+i</strong>RDL~n Temporarily sets the number of times to redial the ISP. The<br />

permanent number of redial attempts will be restored after<br />

completing the next session, whether the session was<br />

successful or not.<br />

<strong>AT+i</strong>RDL? Reports the current value of the number of times to redial<br />

ISP followed by I/OK.<br />

<strong>AT+i</strong>RDL=? Returns the message ―0-20‖ followed by I/OK.
