- #include "ip2types.h"
- // This module is designed to provide a uniform method of sending commands to
- // the board through command packets. The difficulty is, some commands take
- // parameters, others do not. Furthermore, it is often useful to send several
- // commands to the same channel as part of the same packet. (See also i2pack.h.)
- //
- // This module is designed so that the caller should not be responsible for
- // remembering the exact syntax of each command, or at least so that the
- // compiler could check things somewhat. I'll explain as we go...
- //
- // First, a structure which can embody the syntax of each type of command.
- //
- typedef struct _cmdSyntax
- {
- UCHAR length; // Number of bytes in the command
- UCHAR flags; // Information about the command (see below)
- // The command and its parameters, which may be of arbitrary length. Don't
- // worry yet how the parameters will be initialized; macros later take care
- // of it. Also, don't worry about the arbitrary length issue; this structure
- // is never used to allocate space (see i2cmd.c).
- UCHAR cmd[2];
- } cmdSyntax, *cmdSyntaxPtr;
- // Bit assignments for flags
- #define INL 1 // Set if suitable for inline commands
- #define BYP 2 // Set if suitable for bypass commands
- #define BTH (INL|BYP) // suitable for either!
- #define END 4 // Set if this must be the last command in a block
- #define VIP 8 // Set if this command is special in some way and really
- // should only be sent from the library-level and not
- // directly from user-level
- #define VAR 0x10 // This command is of variable length!
- //-----------------------------------
- // External declarations for i2cmd.c

- // Routine to set up parameters for the "define hot-key sequence" command. Since
- // there is more than one parameter to assign, we must use a function rather
- // than a macro (used usually).
- //
- extern cmdSyntaxPtr i2cmdSetSeq(UCHAR seqno, UCHAR size, UCHAR *string);

- extern cmdSyntaxPtr i2cmdBaudRemap(UCHAR dest, UCHAR src);
- extern cmdSyntaxPtr i2cmdBaudDef(int which, USHORT rate);
- // Declarations for the global arrays used to bear the commands and their
- // arguments.
- //
- // Note: Since these are globals and the arguments might change, it is important
- // that the library routine COPY these into buffers from whence they would be
- // sent, rather than merely storing the pointers. In multi-threaded
- // environments, important that the copy should obtain before any context switch
- // is allowed. Also, for parameterized commands, DO NOT ISSUE THE SAME COMMAND
- // MORE THAN ONCE WITH THE SAME PARAMETERS in the same call.
