Sharing a dial up connection for iPhone to connect to

by dsirkka - 7/13/10 7:59 AM

I am at a location where 56K dial up is my only choice (no cell service, satellite is over priced, no cable, no adsl available). I want to be able to share my connection using my wireless internet adapter in my laptop. I have done this with a LAN connection in a hotel room once and it worked nicely. I can't, however, seem to figure it out with a dial up connection. Is it even possible?
I am running Windows 7 Ultimate.
I am fairly computer savvy and have googled for a while. Not a simple task at 26 kbps. Any help would be greatly appreciated.
