**
** How to use this file:
**
** To send a command down a rup, you need to allocate a command block, fill
** in the packet information, fill in the command number, fill in the pre-
** and post- functions and arguments, and then add the command block to the
** queue of command blocks for the port in question. When the port is idle,
** then the pre-function will be called. If this returns RIO_FAIL then the
** command will be re-queued and tried again at a later date (probably in one
** clock tick). If the pre-function returns NOT RIO_FAIL, then the command
** packet will be queued on the RUP, and the txcontrol field set to the
** command number. When the txcontrol field has changed from being the
** command number, then the post-function will be called, with the argument
** specified earlier, a pointer to the command block, and the value of
** txcontrol.
**
** To allocate a command block, call RIOGetCmdBlk(). This returns a pointer
** to the command block structure allocated, or NULL if there aren't any.
** The block will have been zeroed for you.
**
** The structure has the following fields:
**
** struct CmdBlk
** {
** struct CmdBlk *NextP; ** Pointer to next command block **
** struct PKT Packet; ** A packet, to copy to the rup **
** int (*PreFuncP)(); ** The func to call to check if OK **
** int PreArg; ** The arg for the func **
** int (*PostFuncP)(); ** The func to call when completed **
** int PostArg; ** The arg for the func **
** };
**
** You need to fill in ALL fields EXCEPT NextP, which is used to link the
** blocks together either on the free list or on the Rup list.
**
** Packet is an actual packet structure to be filled in with the packet
** information associated with the command. You need to fill in everything,
** as the command processor doesn't process the command packet in any way.
**
** The PreFuncP is called before the packet is enqueued on the host rup.
** PreFuncP is called as (*PreFuncP)(PreArg, CmdBlkP);. PreFuncP must
** return !RIO_FAIL to have the packet queued on the rup, and RIO_FAIL
** if the packet is NOT to be queued.
**
** The PostFuncP is called when the command has completed. It is called
** as (*PostFuncP)(PostArg, CmdBlkP, txcontrol);. PostFuncP is not expected
** to return a value. PostFuncP does NOT need to free the command block,
** as this happens automatically after PostFuncP returns.
**
** Once the command block has been filled in, it is attached to the correct
** queue by calling RIOQueueCmdBlk( HostP, Rup, CmdBlkP ) where HostP is
** a pointer to the struct Host, Rup is the NUMBER of the rup (NOT a pointer
** to it!), and CmdBlkP is the pointer to the command block allocated using
** RIOGetCmdBlk().

** ( reasonable enough ). We can't do this when we spot the
** re-boot, in interrupt time, because the queue is probably
** full. So, when we come in here, we need to test if any
** ports are in this condition, and re-open the port before
** we try to send any more data to it. Now, the re-booted
** RTA will be discarding packets from the PHB until it
** receives this open packet, but don't worry tooo much

** The Scam, based on email from jeremyr@bugs.specialix.co.uk....
**
** To send a command on a particular port, you put a packet with the
** command bit set onto the port. The command bit is in the len field,
** and gets ORed in with the actual byte count.
**
** When you send a packet with the command bit set the first
** data byte (data[0]) is interpreted as the command to execute.
** It also governs what data structure overlay should accompany the packet.
** Commands are defined in cirrus/cirrus.h
**
** If you want the command to pre-emt data already on the queue for the
** port, set the pre-emptive bit in conjunction with the command bit.
** It is not defined what will happen if you set the preemptive bit
** on a packet that is NOT a command.
**
** Pre-emptive commands should be queued at the head of the queue using
** add_start(), whereas normal commands and data are enqueued using
** add_end().
**
** Most commands do not use the remaining bytes in the data array. The
** exceptions are OPEN MOPEN and CONFIG. (NB. As with the SI CONFIG and
** OPEN are currently analogous). With these three commands the following
** 11 data bytes are all used to pass config information such as baud rate etc.
** The fields are also defined in cirrus.h. Some contain straightforward
** information such as the transmit XON character. Two contain the transmit and
** receive baud rates respectively. For most baud rates there is a direct
** mapping between the rates defined in <sys/termio.h> and the byte in the
** packet. There are additional (non UNIX-standard) rates defined in
** /u/dos/rio/cirrus/h/brates.h.
**
** The rest of the data fields contain approximations to the Cirrus registers
** that are used to program number of bits etc. Each registers bit fields is
** defined in cirrus.h.
**
** NB. Only use those bits that are defined as being driver specific
** or common to the RTA and the driver.
**
** All commands going from RTA->Host will be dealt with by the Host code - you
** will never see them. As with the SI there will be three fields to look out
** for in each phb (not yet defined - needs defining a.s.a.p).
**
** modem_status - current state of handshake pins.
**
** port_status - current port status - equivalent to hi_stat for SI, indicates
** if port is IDLE_OPEN, IDLE_CLOSED etc.
**
** break_status - bit X set if break has been received.
**
** Happy hacking.
