at-command

actually I know no thing about serial port. but I see an example of sending it an at-command: echo -e "AT" > /dev/smd0 What is /dev/smd0 and why they sometimes replace it with /dev/ttyS0. /dev/smd0 and /dev/ttyS0 are device files . Such files are virtual files that provide a file I/O operation interface for working with some underlying thing like for instance hardware resources like serial ports, hard disks and memory, or with non-hardware resources like process information, random number input, terminal screen output, etc. Device files comes in two flavours, character and block. Serial ports

Can anyone help me to send and receive SMS using AT commands in Python? In case it matters, I'm using Fedora 8. Which phone will be better with Linux (Nokia, Sony Ericson, Samsung,.....)? Will all phones support sending and receiving SMS using AT commands? Stefano Palazzo Here's some example code that should get you started (in Python 3000): import time import serial recipient = "+1234567890" message = "Hello, World!" phone = serial.Serial("/dev/ttyACM0", 460800, timeout=5) try: time.sleep(0.5) phone.write(b'ATZ\r') time.sleep(0.5) phone.write(b'AT+CMGF=1\r') time.sleep(0.5) phone.write(b'AT

I am trying to send Unicode SMS using at commands and USC2 encoding. But it doesn't work, as I get errors. Here is my inputs: AT OK AT+CSCS = ? +CSCS: ("IRA","GSM","UCS2") AT+CSCS="UCS2" OK AT+CMGF=1 OK AT+CSMP=1,167,0,8 //So this one doesnt work, let's try with 17,167,0,8 ERROR AT+CSMP=17,167,0,8 OK AT+CMGS="+370********" ERROR Or maybe I should use PDU mode to achieve this? I have tried using older modem, and USC2 works in that one, however not in one im using. But im sure this conflicting modem supports USC2. I found I just needed to encode my number in AT+CMGS to UCS2, and now it works: AT
