Pseudo terminals are very convenient for testing purposes, but they are not fully compatible with real serial (or even usb-serial) hardware. With the new option, some workarounds can be enabled to hide the differences and increase compatibility. Although these workarounds shouldn't cause any problems in production builds, the advise is to disable this feature. A few ioctl's are not supported for pseudo terminals. They fail with EINVAL (Linux) or ENOTTY (Mac OS X). Since these specific error codes should not occur under normal conditions, they are simply ignored when pseudo terminal support is enabled. The TIOCEXCL ioctl (exclusive access) is also problematic. The TIOCEXCL setting is shared between the master and slave side of the pty. When the setting is applied on the slave side, it persists for as long as the master side remains open. The result is that re-opening the slave side will fail with EBUSY, unless the process has root priviliges. Since this is very inconvenient, the TIOCEXCL setting is not used when pseudo terminal support is enabled.
