In this mode, the receiver and transmitter interrupts are fully operational. The Modem
Control Interrupts are also operational. However, the interrupts can only be read
using lower four bits of the Modem Status Register (MSR[0-3]) instead of the four
Modem Status Register bits 4-7. The interrupts are still controlled by the IER.
