  The remote control of coherence is a crucial step for its application in
quantum computation. We investigate the maximal steered coherence (MSC) and its
conversion to entanglement in multiple bosonic reservoirs. It is shown that the
MSC decays with time in the Markovian regime and behaves as damped oscillations
in the non-Markovian regime. The MSC can also be connected directly to the
strength of non-Markovianity, through which we show that it can be noticeably
enhanced by taking full advantage of the non-Markovian effects. Besides, the
MSC can be converted completely to entanglement via optimal incoherent
operation applied to the steered qubit and an incoherent ancilla which is
immune of decoherence, and the generated entanglement is stronger than the
shared entanglement in prior. These findings suggest a potential way for
remotely generating and manipulating coherence and entanglement in noisy
environments.
