I need to create a program to send sms through a PORTech MV-374 sms gateway. In the device manual there some AT commands to send sms. They are as follows (please note that they are as exactly as in the manual):

username: voip
password: **** 'the username and password
user level = 1

command: logout, module, module1, module2.
>module1 'choose module
getting module 1 ...
got!!! press 'ctrl-x' to release module 1

ate1 'enter "ate1", then you can see your at command below
at+cmgs="0911123456" 'enter at+cmgs="phone number"
test 'enter short messsage and ctrl+Z
+CMGS: 30

The manual has also given some port numbers as well. They are as follows:
SLAVE 1:8023
SLAVE 2:8123
SLAVE 3:8223
SLAVE 4:8323
