power-up or system reset sets all LCR bits to 0.

3.2.9 MCR - Modem Control Register (R/W)

The Modem Control register controls the interface with the modem or data
set as described below.

For model AP500 and AP520 RTS is directly controlled by a control bit in this
register (a high input asserts this signal).

For model AP521, RTS is used to enable the transceiver to enable output of
TxD. The four modem control inputs (CTS, DSR, DCD, and RI) are
disconnected from their receiver input paths. In addition, the four modem
control outputs (DTR, RTS, OUT1, and OUT2) do not have transmitter output
paths.

Bit-3 of this register must be set to a logic “1” to enable the corresponding
port to issue an interrupt.
