# 3 Terminal Mode Operation

AVRDUDE has an interactive mode called terminal mode that is enabled by the ‘`-t`’ option. This mode allows one to enter interactive commands to display and modify the various device memories, perform a chip erase, display the device signature bytes and part parameters, and to send raw programming commands. Commands and parameters may be abbreviated to their shortest unambiguous form. Terminal mode also supports a command history so that previously entered commands can be recalled and edited.
