Line 17: ===DTR configurability on modems=== Virtually all newer{{when}} modems have a built-in capability of modifying what they do with RS-232 signals, depending on the application. The [[AT command]] for manipulating DTR is typically <code>AT&D</code> followed by a single digit. More frequently, the setting is buried in a longer [[initialization string]] - such as <code>AT&F'''<u>&D2</u>'''&C1S0=0X4</code>. Note that per the [[Hayes command set\|specifications]], AT commands can be [[concatenation\|concatenated]] together by only specifying the characters "AT" once, followed by all the remaining commands strung together<ref name="Hayes">[[Hayes command set]]</ref>. * '''AT&D''' or '''AT&D0''' - Ignore DTR signal. A call will continue regardless of the DTR line, and the only way to end the call is with the escape sequence, or if it gets terminated by the other side. This setting is only used if the computer equipment cannot provide or control DTR.
