Format 3 — Send Special Character Command
This command causes one of the pre-programmed characters in the special character registers
(SCHR1, SCHR2, SCHR3, and SCHR4) to be sent preemptively (applies to the serial channels
only). The character sent is selected by the settings of bits 2 through 0. ‘Preemptively’ means that
the special character is sent immediately following the character in the Transmitter Holding
register; it does not wait until the FIFO empties. Once the special character is sent, transmission of
any characters remaining in the FIFO proceeds normally.
Description
