Configuring Your Modem’s Country Code
After following the steps for your operating system and after the system has re-
started, you may need to issue an AT Command to configure the modem to use the
PSTN (Public Switched Telephone Network) of your country. The modem can be
configured for: Canada, Japan, and the United States.
To configure the modem’s country setting, open a terminal program such as Hyper
Terminal. At the command prompt, type: at<enter>. The response should be “OK”.
Now type one of the following commands depending on the country where the
modem will be operated.
Canada: at%T19,0,1c<enter>
Japan: at%T19,0,10<enter>
United States: at%T19,0,19<enter>
If the command was properly entered, the response will be “OK”. A response of
“ERROR” will indicate an incorrect entry. After the command has been entered
and accepted, the modem will default to this setting every time you turn on the
system. To find your current country setting, issue the command ATI9<enter>.
The response will indicate your current country setting (Canada, Japan, or North
America).
