TPC (The Phone Company) offers a text only option for sending a fax. You can paste your text through a browser interface and have it sent to a fax machine. Alternatively, you can send a text email to a special email address, and it will format and send the text content as a fax to any fax machine in the U.S.
Send faxes? Yes, but it is limited to simple text (copied/pasted into web browser form or through email text)
Receive faxes? No.
