RAS Server Parameters
+iRAR - RAS RINGs
+iRAU - Define RAS Login User Name
Syntax: AT+iRAR=n
Sets the number of RINGs that will activate W24's internal RAS
if RAU is not empty.
Parameters: n = number of RINGs W24 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,
W24 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, W24 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 W24 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.
AT+iRAR? Returns RAR's current value. The reply is followed by I/OK.
AT+iRAR=? Returns the message '2-20'. The reply is followed by I/OK.
Syntax: AT+iRAU=user

Parameters: user = User Name to be used for authentication when accepting a
call from a PPP client connecting to W24's internal RAS.
Command Options:

user=<user-name> user-name will be used to establish login rights of a remote PPP
client connection to W24's internal RAS.
