Start a communications software package, such as Hyperterminal, Quick
Link II or MacComCenter. Adjust the settings, if necessary, so you can
send AT to your modem and get an OK response.
If you are sending the file from a Macintosh computer, make sure you do
not transfer the file in MacBinary format. In MacComCenter, for example,
select Setup | File Transfer.... Under MacBinary options, select Never
MacBinary.
