The first line of the layout response is the scanf-like parameter list for
parsing the fields from an ASCII erec response. Parameters are separated by
spaces and the line is terminated by a “\n” (the normal line separator
character). Valid fields are:
%s - parse a string
%d - parse a decimal number
%ld - parse a long (32-bit) decimal number
%f - parse a floating point number
%x - parse a hexadecimal number
%lx - parse a long (32-bit) hex number
%* - ignore the field
Note
Signed versus unsigned for the integer values does not matter; it is
handled automatically.

The second line of the layout response is the binary parameter list for
parsing the fields from a binary response. Parameters MUST be separated
by spaces, and the line is terminated by a '\n'. Valid fields are:
t - parse a time specifier (2 bytes)
D - parse a date specifier (3 bytes)
i - ignore one 8-bit character (1 byte)
e - parse a 24-bit floating point number (3 bytes: n/x)
E - parse a 24-bit floating point number (3 bytes: N/x)
f - parse a 32-bit floating point number (4 bytes)
c - parse an 8-bit signed number (1 byte)
C - parse an 8-bit unsigned number (1 byte)
n - parse a 16-bit signed number (2 bytes)
N - parse a 16-bit unsigned number (2 bytes)
m - parse a 24-bit signed number (3 bytes)
M - parse a 24-bit unsigned number (3 bytes)
l - parse a 32-bit signed number (4 bytes)
L - parse a 32-bit unsigned number (4 bytes)
There is an optional single digit
d
which may follow any of the numeric
fields, which indicates that after the field has been parsed out, the resulting
value is to be divided by 10^
d
. Thus the 16-bit field 0xFFC6 would be
interpreted with the format specifier 'n3' as the number -0.058.
The subsequent lines in the erec layout response describe the appearance of
the full panel. The full instrument panel as it appears on the screen has two
