S.C. Code § 27-37-150
After the commencement of ejectment proceedings by the issuance of a rule to vacate or to show cause as herein provided, the rental for the use and occupancy of the premises involved shall continue to accrue so long as the tenant remains in possession of the premises, at the same rate as prevailed immediately prior to the issuance of such rule, and the tenant shall be liable for the payment of such rental, the collection of which may be enforced by distress as herein provided with respect to other rents. But the acceptance by the landlord of any rent, whether it shall have accrued at the time of issuing such rule or shall subsequently accrue, shall not operate as a waiver of the landlord's right to insist upon ejectment, nor as a renewal or extension of the tenancy, but the rights of the parties as they existed at the time of the issuance of the rule shall control.
