//=================================================================
46
// This class deals with resetting a target.
47
// The ctor accepts the "reset string" this is something like
48
//    expect($T05,#) 3(off(ginga:5000,a1) delay(2000) on(,..com2,38400))
49
// and is parsed to generate the commands to reset the target.
50
// The syntax is:
51
//    resetstring :== [directive | <integer>(resetstring)] * 
52
//    directive   :== id(arg[,arg]*)
53
//    directive   :== port | action | delay | expect
54
//
55
// The <integer>(string) syntax repeats argument its until reset is achieved.
56
// Each directive is given by example below:
57
// expect: 
58
//   Expected string(s).            e.g. expect(str1,str2,...).
59
//   Arguments:
60
//     The string(s) expected to be output by a target after reset.
61
//     *all* supplied strings must be present *in order* in the reset string for a reset to be recognized as valid.
62
// port:
63
//   Provide port information to apply to all subsequent off|on|on_off|off_on actions until overwritten.
64
//   e.g. port(com1,38400,1000)
65
//   Arguments:
66
//     0. Port
67
//     1. Baud
68
//     2. Read timeout
69
//   These have the meanings described under off|on|on_off|off_on.
70
// off|on|on_off|off_on:
71
//   Request a reset host to perform a "power cycle" (or its logical equivalent - 
72
//   the meanings of "off" and "on" may depend on the reset host)
73
//   e.g. off_on(ginga:500,A4,com1,38400,10000,1000)
74
//   Arguments:
75
//     0. Reset host:port
76
//     1. Control string (meaning known to the reset host)
77
//     2. Port (from which to read startup output)
78
//     3. Baud for the above
79
//     4. Read timeout
80
//     5. Delay (between off and on or vice versa)
81
// delay:
82
//   Delay for a given time right now.      
83
//   e.g. delay(1000)
84
//   Arguments:
85
//     0. msec to delay
