In case XON/XOFF software flow control function and Xon Any function is enabled,
descriptions are as follows.

In case Software flow control function and Special character function is enabled,
descriptions are as follows.

If Xon, Xoff characters are used as one character,
If Xoff character arrives during XON status, status changes to XOFF.
If Xon character arrives during XOFF status, status changes to XON.
If Xoff character arrives during XOFF status, status changes to XON but Xoff
character is not treated as data.
If only Xon1 or Xon1 + Xon2 character arrives during Xoff status, status changes to
Xon and all characters are not treated as data.
If only Xon2 character arrives during Xoff status, status changes to Xon and Xon2
character is treated as data and stored in RX FIFO.
If Xoff1 + Xoff2 character arrives during XON status, status changes to XON.
If Xoff1 + Xoff2 character arrives during XOFF status, status is changed to XON by
Xoff1 and changed to XOFF again by Xoff2.
If Xoff1 character is used as Software flow control character, character in Xoff2
Register is recognized as Special character.
If Xoff2 character is used as Software flow control character, it is not recognized as
Special character but as Xoff character because both are same.
If Xoff1, Xoff2 character is sequential and Xoff1 + Xoff2 character is used as
Software flow control character, it is not recognized as Special character but as Xoff2
character because both are same.
If Xoff1 + Xoff2 character is used as Software flow control character and Xoff2
character which does not follow after Xoff1 character arrives, it is not recognized as
Xoff2 character but as Special character even though both are same.
