Yes, and what's the exact question ? Where are you stuck exactly ? You already asked a similar question yesterday and you got some answers, so where is the problem ? (And please, avoid using SMS language, because it is quite difficult to read for non native english speakers).

trn f cmd eko md n th mdm Er, Turn off the Command Echo mode on the modem. A modem will either echo back the command you send it (E1) or not (E0). Type in "ATE0" It will echo back. Type in another AT command. It should not echo. Read the modem commands in the manual if this is not clear. It is probably working correctly.

Once you opened the port with CreateFile, you can use ReadFile to read data from the serial port and WriteFile to write data on the port. Take a look at this article[^] for complete information. Take a look also at this section[^] that contains several articles about serial port communication (and some wrapper classes too, to make your life easier).

It's difficult for us English-ians too!
