| 4 | Subject: [PATCH] Compile with libc's without cispeed / cospeed |
| 5 | |
| 6 | Some libc implementations (e.g. musl) do not define the cispeed and |
| 7 | cospeed struct termios fields. So we have to check the |
| 8 | _HAVE_STRUCT_TERMIOS_C_ISPEED and _HAVE_STRUCT_TERMIOS_C_OSPEED |
| 9 | macros. If not defined, we disable custom baudrate support. |
