SMS using ethernet port modem

[rociologa]

Hello,

I`m trying to send SMS using a Multitech mutimodem GSM/GPRS MTCBA-G-EN-F4-ED. I have achieved to send SMS using Hyperterminal, but first of all I`ve had to introduced user/password.

Once I send SMS using VISA and AT commands but it was with a another modem, a serial port modem Wavecom; now with ethernet, I have problems.

Some ideas?

Thanks in advance!
