	Pin	Signal	Signal Name and Description
	Number	Mnemonic	Signal Name and Description
	Number	Mnemonic

	22	RI	RING INDICATOR. Output from the modem to the terminal;
			indicates to the terminal that an incoming call is present. The
			terminal causes the modem to answer the phone by carrying
			DTR true while RI is active.

	23		Not used.

	24	TxC	TRANSMIT CLOCK (DTE). Input to modem from terminal;
			same function as TxC on pin 15.

	25	BSY	BUSY. Input to modem from terminal. A positive EIA signal
			applied to this pin causes the modem to go off-hook and make
			the associated phone busy.

Levels of Implementation

There are several levels of conformance that may be appropriate for typical EIA-232-D interconnections. The bare minimum requirement is the two data lines and a ground. The full implementation of EIA-232-D requires 12 lines; it accommodates:

❏Automatic dialing

❏Automatic answering

❏Synchronous transmission

A middle-of-the-road approach is illustrated in Figure E-1.
