Online is a VT100 terminal emulator for the PalmPilot organizer. Users of Online can connect to other computer systems and access real computer power and network resources wherever they are. Online has been used to connect to Unix systems and then surf the web using Lynx, edit files with vi and emacs - and even to read and write email using elm. Online can be connected to either a modem or the serial port of another computer or device (such as a hub or router). If connecting to a modem use the Pilot modem cable available from Palm. It is possible to use the cradle or serial cable and a null-modem connector to connect to some modems, but this doesn't seem to work for all.
