SMS Server Tools

Hardware compatibility

My Software needs a GSM modem with SMS command set according to the european specifications GSM 07.05 (=ETSI TS 300 585) and GSM 03.38 (=ETSI TS 100 900).

When a vendor writes "SMS command set" without giving the specification names, then the device typically supports a subset of this specification. In this case you can surely send 7bit text messages and you can probably receive them. But its not sure, if status reports, binary messages or unicode messages work.

Mobile phones have more often compatibility issues than real GSM modems.

Many USB devices are not supported by Unix operating systems.

The following list is incomplete. It shows devices that are reported as well working:

Probably all mobile phones support status report but you cannot read them out with a computer. Status reports appear only on the phones display.

Serial adapter and converter

USB2Serial adpater cables, based on Prolific PL2303 chip
USB2Serial adpater cables, based on FTDI chips
USB2Serial adpater cables, based on Silabs CP2102 chip
Digi Etherlite ethernet to serial
Equinox multi Serial PCI cards

Note 1)
You must cut pin 4 (wich is DTR) of the serial connector because the phone disables AT command set if the pin is connected and active. The GM22 does not support ascii mode. Mode=new and baudrate=9600 are the correct settings.

Note 2)
Replace put_command("AT+CREG?\r"...with put_command("AT+CREG?\n"... in modeminit.c. Set baudrate=115200 and mode=new. This phone was reported as unstable by one user.

Note 3)
Enter "memory_start=0" into the config file. If you removed the PIN protection from your SIM card, this modem says that the PIN is locked, which is not true. Remove the pin=1234 line from the config file, then the program will ignore that instead of stopping with an error message. The linux driver for 3G/UMTS version can be loaded with the command "modprobe usbserial vendor=0x0af0 product=0x5000". I assume that loading the driver works similar for the other versions of that card. The device name is /dev/usb/ttyUSB0.

Note 4)
On Linux, this Modem needs the HSO driver. Disable hardware handshake with rtscts=no. When you need to receive messages, set the option memory_start=0.
