DLE is also used lightly in communication from the computer to the modem. One specific DLE event signals the end of a fax page, or the end of an audio file. That event returns the modem back into command mode. Unlike in standard dial-up data mode, dropping DTR isn't an appropriate way to resume command mode since a hangup is not desired, and an escape code with mandatory pauses isn't suitable either. Because of this, literal 0x10 bytes in data are doubled from the computer to the modem as well.
