1. Wildcard commands now support ? in device spec (e.g. DSK?: or DSK??:); previously, only * was supported within the device.
2. (UNIX) A new variation of the XONXOFF=<bool> option is now supported:
XONXOFF=ALWAYS
Normally (with XONXOFF=ON), the XON/XOFF protocol support is still disabled when you are at within an input operation, since ^S often has a different meaning in the context of expected input. But that can cause a problem in some cases when the disabling of XON/XOFF at the start of an input operation occurs too quickly after a large amount of output, some of which may still be buffered. This usually was most noticeable with DIR/W [] where it would handshake properly until just before the very end (where it returned to the command input prompt before all of the output was fully delivered to the terminal. Note that the downside of XONXOFF=ALWAYS is that you won't be able to ever use any input commands that being with ^S. (You can avoid all of these XON/XOFF-related problems by just using hardware handshaking.)
