Your first BBS call, step by step

If you never dialed a BBS, the experience is easier to understand as a sequence of decisions than as a piece of mysterious machinery. Your computer wasn't opening a website. It was asking a modem to place an ordinary telephone call and turn audio signals into data.

1. Find a number to call

Before search engines and centralized directories became common, computer clubs, magazines, friends and other BBSs supplied phone numbers. Listings might tell you the board's name, location, speed, operating hours, specialty and whether registration was open. A number in your own local calling area was often desirable because long-distance telephone charges could add up.

2. Configure your communications program

Programs such as Telix, Qmodem, Procomm Plus and other communications packages provided dialing directories and terminal emulation. You chose a serial port, selected a speed compatible with your equipment, and set terminal preferences such as ANSI display and flow control. The common-looking setting 8-N-1 meant eight data bits, no parity and one stop bit.

Hardware details mattered. The modem might be an internal card or an external box connected to a serial port. A telephone cable connected it to the wall jack. Sharing a household phone line had consequences: anyone picking up the telephone could interrupt the call.

3. Dial and wait for a carrier

Many Hayes-compatible modems understood AT commands. For example, ATDT followed by a telephone number instructed the modem to dial using touch tones. It first placed the call, then attempted to negotiate a data connection with the answering modem.

The sample above is illustrative. Actual result codes and welcome screens varied by modem, software and BBS.

4. Introduce yourself

On a first call, the BBS often asked for a name or handle, password and other registration details. Some systems automatically gave newcomers basic access. Others requested contact information or required manual SysOp validation before certain message areas or downloads opened.

5. Explore the menus

Most boards had a main menu with command letters: read messages, write a message, list files, download, launch a door game, view bulletins or page the SysOp. Advanced commands often became second nature. A frequent caller could navigate a whole board with a short sequence of keystrokes.

6. Leave the line for somebody else

When you were finished, a goodbye command disconnected the call gracefully. If the connection dropped unexpectedly, you might see the stark modem response NO CARRIER. On a crowded one-line system, your departure meant another caller could finally get through.

That experience can be recreated today with Telnet-capable terminal clients and participating hobby BBSs, although secure transports such as SSH are preferable when offered and old software should not be exposed to the public Internet without hardening.
