When using a software flow control the Xon/Xoff characters cannot be used for data transfer.

EFR[5]
Special Character Detect.
Logic 0 = Special character detect disabled (normal default condition).
Logic 1 = Special character detect enabled. The SC16C2550 compares
each incoming receive character with Xoff2 data. If a match exists, the
received data will be transferred to FIFO and ISR[4] will be set to
indicate detection of special character. Bit-0 in the X-registers
corresponds with the LSB bit for the receive character. When this feature
is enabled, the normal software flow control must be disabled (EFR[3-0]
must be set to a logic 0).
Enhanced function control bit. The content of IER[7-4], ISR[5-4], FCR[5-4],
and MCR[7-5] can be modified and latched. After modifying any bits in the
enhanced registers, EFR[4] can be set to a logic 0 to latch the new values.
This feature prevents existing software from altering or overwriting the
SC16C2550 enhanced functions.
Logic 0 = disable/latch enhanced features. IER[7-4], ISR[5-4], FCR[5-4],
and MCR[7-5] are saved to retain the user settings, then IER[7-4]
ISR[5-4], FCR[5-4], and MCR[7-5] are set to a logic 0 to be compatible
with SC16C554 mode. (Normal default condition.)
Logic 1 = Enables the enhanced functions. When this bit is set to a
logic 1, all enhanced features of the SC16C2550 are enabled and user
settings stored during a reset will be restored.
Cont-3-0 Tx, Rx control. Logic 0 or cleared is the default condition.
Combinations of software flow control can be selected by programming
these bits. See
Table 21
