SMS - Short Message Service [[is that right?]]

Does anyone have code to send text messages from a Tcl program to 
a cell phone?

[Zarutian] 26. may 2005: I wrote a little proc to send a SMS message to a cell phone sometime ago but I cant find it now.
It was realy simple. It used an form on a cell phone provider's website.
Mind you it could only send SMS message to Icelandic cell phones.
Maybe I will figure it out again, during the weekend or after the weekend ;-)
