+		** loaded from 0x7FFF downwards. We have loaded it
+		** at some other address. The startup code goes into the small
+		** ram window at Sram2, in the last 8 bytes, which are really
+		** at addresses 0x7FF8-0x7FFF.
+		**
+		** If the loadbase is, say, 0x7C00, then we need to branch to
+		** address 0x7BFE to run the host.bin startup code. We assemble
+		** this jump manually.
+		**
+		** The two byte sequence 60 08 is loaded into memory at address
+		** 0x7FFE,F. This is a local branch to location 0x7FF8 (60 is nfix 0,
+		** which adds '0' to the .O register, complements .O, and then shifts
+		** it left by 4 bit positions, 08 is a jump .O+8 instruction. This will
+		** add 8 to .O (which was 0xFFF0), and will branch RELATIVE to the new
+		** location. Now, the branch starts from the value of .PC (or .IP or
+		** whatever the bloody register is called on this chip), and the .PC
+		** will be pointing to the location AFTER the branch, in this case
+		** .PC == 0x8000, so the branch will be to 0x8000+0xFFF8 = 0x7FF8.
+		**
+		** A long branch is coded at 0x7FF8. This consists of loading a four
+		** byte offset into .O using nfix (as above) and pfix operators. The
+		** pfix operates in exactly the same way as the nfix operator, but
+		** without the complement operation. The offset, of course, must be
+		** relative to the address of the byte AFTER the branch instruction,
+		** which will be (urm) 0x7FFC, so, our final destination of the branch
+		** (loadbase-2), has to be reached from here. Imagine that the loadbase
+		** is 0x7C00 (which it is), then we will need to branch to 0x7BFE (which
+		** is the first byte of the initial two byte short local branch of the
+		** download code).
+		**
+		** To code a jump from 0x7FFC (which is where the branch will start
+		** from) to 0x7BFE, we will need to branch 0xFC02 bytes (0x7FFC+0xFC02)=
+		** 0x7BFE.
+		** This will be coded as four bytes:
+		** 60 2C 20 02
+		** being nfix .O+0
+		**	   pfix .O+C
+		**	   pfix .O+0
+		**	   jump .O+2
+		**
+		** The nfix operator is used, so that the startup code will be
+		** compatible with the whole Tp family. (lies, damn lies, it'll never
+		** work in a month of Sundays).
+		**

+** 
+** 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 processore 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().

+** 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, then the first
+** data byte ( data[0] ) is interpretted 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 analagous). 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.
