Can anyone tell me if there is a brand of GSM phone (other than Sony Ericsson) that there are RS232 (DB9 connector) data cables readily available for?

Most phones now only support USB cables, but I need to test with phones that still support RS232 cables (to connect to specialised devices).

I guess that the other option would be some sort of converter, but I'm not too sure how successful that would be? I know that you can get a USB<->RS232 converter cable, but that needs a driver (and the devices that I will be connecting to cannot take a standard PC driver).

Any suggestions would be appreciated.

Kind Regards,

Nigel H.

This may be alittle off course, but WaveCom do a GSM module that has a rs232 connector. The wavecom is more a device for embedding along with a microprocessor etc.

Nokia have a similar module called the H12 or similar.

Heaps of brands have data cables available for them. Actually getting them in NZ (especially at a reasonable price) is another story. Check out this site .

I agree that there are plenty of data cables around, but there are very few that have DB9 connectors (ie NOT USB).

I tried looking at the site you mentioned and they've exceeded their bandwidth allowance...

I think the answer will be to just recommend Sony Ericsson - which suits me fine as their Bluetooth seems to be the most compatible as well 8-).

Hmm, didn't plan on that happening. Yes there are heaps of serial cables. To upgrade firmware on most phones, you require a serial cable so they are available. Do a google search and you should be able to find them easily enough. Nokia has a couple of models which can be hooked up using a serial cable, more info at bottom of this page,,34250,00.html#dlr2l . Otherwise more cables here,, .

I don't know what your level of electronics knowledge is but if you're after something for a custom project you can get RS232 cellular modules from these guys that look pretty cool including one with a built in Python interpreter built in which sounds very cool..
