================
Comment at: lldb/source/Host/common/Terminal.cpp:316-347
+  bool parity_bit = true;
+  bool odd_bit = false;
+  bool stick_bit = false;
+
+  switch (parity) {
+  case Parity::No:
+    parity_bit = false;
----------------
I am wondering if we can avoid the double conversion (enum->bools->flags). Would something like this be shorter/cleaner:
```
unsigned(?) GetParityFlagMask() {
  return PARENB | PARODD
#ifdef CMSPAR
    | CMSPAR
#endif
  ;
}
Expected<unsigned> GetParityFlags(Parity) // error if parity not supported

SetParity(parity) {
getParityFlags(parity); // and check result
GetData(); // and check result
data.m_termios.c_cflag &= ~GetParityFlagMask();
data.m_termios.c_cflag |= flags;
SetData();
```


================
Comment at: lldb/unittests/Host/posix/TerminalTest.cpp:187-189
+                    llvm::Failed<llvm::ErrorInfoBase>(testing::Property(
+                        &llvm::ErrorInfoBase::message,
+                        "space/mark parity is not supported by the platform")));
----------------
btw, we have `FailedWithMessage` for this these days.
