Once the computer makes the connection, the user at the remote site runs the applications on the host computer, just as if sitting at the office computer. You can run programs, transfer files back and forth, print on the office printer, and if the host computer is on a network, you can access the files across the network if you have the required access rights. The speed of the modem is equally important. The information transferred between computers is serial, that is, one character at a time. Higher speeds are available but for the types of applications usually accessed remotely in law offices, these speeds are sufficient.
Prices vary, depending upon the modem brand and the computer dealer selling it.
Because prices are this low, I don't recommend purchasing anything lower than a 9600 baud modem. I'm not sure if you can purchase a 300 baud modem. The 2400 baud modem will continue to be popular, but the speed of the applications running over the modem will require the user to use higher speed modems. Modem speeds do not have to match at both ends. However, the communications and data transfer will occur at the slowest speed available.
