Is there a phone that can be used to send SMS while being charged? Perhaps some kind of a special cable that combines data and power? For stationary application, this is necessary. Obviously external GSM modem would be a solution, but the phone solution would be cheaper, if possible.

Thanks!

Most phones that I've seen support this ...

Certainly Nokia and SonyEricsson models that I have used. (SonyEricsson cables cover the power input ... but you can plug the power input into the cable itself.)

Com ports won't have power, and most of USB ports and/or cables can't charge the batteries, either. It also depends on the phone's battery

Disassemble the comport connector that plugs into the phone. make sure that the connector has the pins for power (compare the pins with the charger connector)

determine polarity with the probe

cut the connector from the charger cable and solder the power wires to the power pins on ur com-port connector.

A bit of soldering....
and u won't have to ask anyone to remove or charge the batteries

try
www.falcom.de
and look at their FALCOM TWIST-USB-SET

this uses the USB for power and the connection to the computer.
I've been using this happily for the past year.

Better solution:

Get a PCMCIA GSM card, such as Nokia Cardphone, Sierra Aircard 750, Merlin G201 or Ericsson GCxx cards. To stick it into a desktop PC yu will need a PCI to PCMCIA Cardbus adapter. If you're running Windows it's a snap to make it all work. It works much faster and is absolutely stable, unlike most handsets. Dunno about Unix-based platforms, you'll have tough time looking for drivers..

External modems such as Falcom, Wavecom, Siemens or Xircom with a serial cable connection are another good solution, albeit a bulkier and a slower one. Falcom makes some fantastic stuff now, some modules allow for IP-based applications run within the module itsef. Check out their Web site, Falcom.de

Adapters cost about $30, used cards between 20 and 100 Euros on Ebay, mostly in Germany, some in the U.K. Terminals start at about 120EUR. Most sellers would ship outside the EU, even if they claim they won't

A dedicated GSM modem device is always a better solution.

But I don't understand what the issue is here in the first place. The cables for Nokia and SonyEricsson phones allow for the phone to be plugged in to AC power at the same time that the data cable is connected.

Perhaps not all phones are like this ... and those should definitely be avoided.
