thanks Lonny, I enabled local echo.

[toyo ayeni]

GET / HTTP/1.1<cr><lf>

Host: http://www.yahoo.ca<cr><lf&gt;

When I start with ‘G’ I expect to see G on the screen, then ‘E’ then ‘T’ and so on. But nothing comes up. After a few seconds the NO CARRIER response comes up.

hi Lonny,

I’ve run into a different kind of problem. As an example, after issuing the (#SD) command to http://www.yahoo.ca @port 80, I get the ‘CONNECT’ response. Then I try to issue HTTP commands to retrieve the page but the characters are not echoing back. It seems like the module is locked up. After a few seconds, I get the ‘NO CARRIER’ response. I can ping (#PING) the site, I can send email using the other method (#EMAILD).

Any suggestions? (I’ve posted my sequence of commands below) =>

hi Lonny

I found my problem. I had been using an APN of the carrier that did not require a user name/pwd. so soon as a switched to an APN that required it, it worked.

thanks anyways
