11. MODEM CONFIGURATION
Raymar-Telenetics leased line modems are based on Rockwell chipsets. These chipsets contain
Rockwell’s “AT” command set.
Unless otherwise specified at the time of order, your modem will have left the Raymar-
Telenetics factory in the configuration detailed on the following pages.
(a)
The Raymar-Telenetics factory configuration differs from the Rockwell default
configuration as follows.
&C0 Rockwell Default Carrier Detect (CD) always ON
&C1 Raymar-Telenetics Factory Carrier Detect (CD) only ON when modem
connected (on hook)
(b)
Raymar-Telenetics has modified the following Rockwell command
&R0 Rockwell Default CTS follows RTS with a 1ms - 5ms delay
&R0 Raymar-Telenetics CTS follows RTS with no delay
Modification
(c)
Raymar-Telenetics has added the following new AT Command to the MIU14.4L
Dumb Mode Feature (\S0, \S1)
In Dumb Mode, the modem will not respond to any received data, including AT commands.
Dumb mode is useful if there is any possibility that a device connected to the modem will try to
send data while the modem is in it’s connect sequence (such data will abort the connection
sequence).
A password must be entered prior to using Dumb Mode. Modems are shipped without a
password. To record a password, enter AT&Z3=password&W<enter> (substitute your
preference for “password”, it is case sensitive).
To enter dumb mode, type ATpassword<enter>, followed by AT\S1<enter>. (This entire
sequence must be entered within 10 seconds).
To exit dumb mode there are two possible methods:
1.
Enter ATpassword<enter>, then AT\S0<enter>, within 10 seconds.
2.
Power modem off, power on, you have 20 seconds to enter ATpassword<enter>,
then AT\S0<enter>
