GSM cell phone with RS232 data interface ??

Started by Unknown March 4, 2009
Does anyone know of a modern GSM phone which still has an RS232
data cable available for it ? (Most have gone to USB .. I want to send
SMS
messages from my embedded device which only has a RS232 port)

Thanks,
   Stuart

Most of the USB data cables I have examined are USB-RS232 converters. I daresay the majority of cellphones still have "RS232" (meaning async 3-wire serial, with 3.3V or 1.8V inverted signal levels.

Why not get a GSM module which has serial port normally TTL like levels see for example <http://www.roundsolutions.com/gsm/>

I was searching for one of these as well at one point, but all the phones I found had been discontinued. You could always use one of these: http://www.multitech.com/PRODUCTS/Families/MultiModemGPRS/ They're a bit expensive but they seem to work well (except for a quiet but irritating hissing noise coming from the power supply). If you're planning on building many devices, then you might consider using a GSM module. They're cheaper but you have to add your own antenna, power supply, SIM socket, enclosure, etc.

Some of the low-end motorola phones sold recently as AT&T go phones had that feature, i think it was through the headphone jack.

Yes. You want something like a Wavecom m1206b modem.
