33.9 RAS Server Parameters
Nonvolatile Parameter Database
33.9.1 +iRAR — RAS RINGs
Syntax: AT+iRAR=n Sets the number of RINGs that will activate
iChip‘s internal RAS if RAU is not empty.
Parameters: n = number of RINGs iChip will detect before
answering an incoming call and activating its
internal RAS.
If n is set to a value greater than 100 and an
incoming call is picked up by the host or the
modem after less than n-100 RINGs, iChip will
activate its internal RAS.
The RAS server will negotiate a PPP connection if
a ‗~‘ is received as the first character from the
modem after the CONNECT line to indicate a PPP
packet. Otherwise, iChip will revert to transparent
mode communications, allowing the host to
conduct direct modem to modem data transfer.
Command Options:
n = 2 .. 20
+100 Add 100 to any RAR value to force iChip to
activate its internal RAS even if the call was
picked up by the host or the modem (if a ‗~‘ is
received as the first character from the modem
after the CONNECT line to indicate a PPP packet).
Default: n = 4
Result code:
I/OK If n is within limits.
I/ERROR Otherwise.
