Whether you’re connecting from a

serial terminal program or have

programmed a microcontroller to

make the connection, you can use this

program to test whether the Lantronix

module is making a successful con-

nection. Once you’ve seen messages

coming through to this program in

the right sequence, just change the

connect string in your microcontroller

code to the address of the web server

you want to connect to, and everything

should work fine. If it doesn’t, the

problem is most likely with your web

server. Contact your service provider ...
