Not Subject to NDA
For USB ports, receiving input data has the same effect of a low to
high level transition. Therefore, if the DTR is not asserted, or if it is
asserted but its level has not been signaled by the DTE to the DCE,
after receiving input data the DTR is considered asserted. A new
DTR level transition from asserted to not asserted will block again
the outbound flow.
USIF ports without DTR pin only support <n>=0.
This command is available when #M2MATP is '1'.
AT#DTR?
Read command returns the current of <n> parameter.
AT#DTR=?
Test command returns the list of <n> values in the format:
#DTR: (list of <n> values)
For USB port:
AT#DTR=?
#DTR: (1,2)
