RE: Creating modem chat script

["Mark Tinka" <mtinka at africaonline.co.ug>]

Perhaps a generic chat script should do just fine for you; take a look at
this:

chat-script REMDEVICE ABORT ERROR ABORT BUSY "" "ATZ" OK "ATDT \T" TIMEOUT
30 CONNECT \C

Just to give you an indication for some these parameters:

REMDEVICE will drop any connection if the modem declares a busy or error
condition. If this condition is not present, the router will wait for the
string "".

\T inserts a phone number from your dial string or dial map into the chat
script. Please watch the casing here, it's very important, as a \t will do
something else altogether - it will cause the script to look for a table
character. Please maintain the casing for the entire chat script as shown
above.

The router will then issue an ATZ [modem reset] command. The modem will then
respond OK to the ATZ command, which is normal. The router will then send
the ATDT command and replace \T with a phone number to call from your dial
string or dial map.

TIMEOUT means that the call is considered unanswered if no carrier is
detected within 30 seconds. Once a connection is established, the chat
script sends a \C, which is a carriage return <cr>.

Subject: Creating modem chat script


	Hi,
I am interested for creating multitech modem caht script under cisco IOS
v11 for customer dialings. I had an example script for init and reset a
US Robotics Courier modem like :

!
chat-script init-courier ABORT ERROR "" "AT&F1S40=6S0=1&W" OK "ATZ"
chat-script reset-courier ABORT ERROR "" "AT&F1S40=6S0=1&w" OK "ATZ"
!
The ISP received new multitech modems to extand dialing access. Can I
use the same chat scrit to initialize and reset these modems like the
USR Courier ?


Tanks for your answers, and have fun ...
