===Suggested Methods of Access===
You have access to a variety of computer systems depending on the accessories used with the Home Computer and Terminal Emulator II Command Module. The following diagrams illustrate two typical arrangements.
====Accessing Subscription Data Services or a Remote Computer System====

Generally, your Home Computer will communicate with a subscription data-base service or other remote system over the telephone lines, as shown here. In this situation, your Home Computer system needs the TI RS232 Interface and the TI Telephone coupler (Modem) - or other RS232C-compatible modem - to communicate with the other system. If your computer is located near the other system, you may be able to communicate with the other system by direct cable. The direct cable eliminates the need for modems and telephone calls, but the RS232 Interface is still required. (See the TI RS232 Interface owner's manual for information on linking your computer to the other system by direct cable.)
''Note:'' To access a data-base service, you must subscribe to the appropriate service and pay any required fees. Most computer-related magazines include information on available data-base services.
