i'm writing some code to simulate the boot progress after power on
but when i try to read the 2nd sector from a floppy disk, this operation always fail with ah=0x80h which means timeout, how can i get over this problem?
my code would be like this:
looking forward to replies.
really appreciate any suggestion.
any idea on how to timeout the read statement for ksh?
for bash u can use read -t option
-t timeout

line of input is not read within timeout seconds. This
option has ... (2 Replies)

I saw several thread for this issue but none addresses my issue.
I have tried read -t but the result is read bad options
My requirement is

2. If input = y or no input in 60 seconds

INTRO(3) Library Functions Manual INTRO(3)NAME
intro - introduction to library functions
SYNOPSIS
#include <stdio.h>
#include <math.h>
DESCRIPTION
This section describes functions that may be found in various libraries, other than those functions that directly invoke UNIX system primi-
tives, which are described in section 2. Functions are divided into various libraries distinguished by the section number at the top of
the page:
(3) These functions, together with those of section 2 and those marked (3S), constitute library libc, which is automatically loaded by
the C compiler cc(1) and the Fortran compiler f77(1). The link editor ld(1) searches this library under the `-lc' option. Declara-
tions for some of these functions may be obtained from include files indicated on the appropriate pages.
(3M) These functions constitute the math library, libm. They are automatically loaded as needed by the Fortran compiler f77(1). The link
editor searches this library under the `-lm' option. Declarations for these functions may be obtained from the include file
<math.h>.
(3S) These functions constitute the `standard I/O package', see stdio(3). These functions are in the library libc already mentioned.
Declarations for these functions may be obtained from the include file <stdio.h>.
(3X) Various specialized libraries have not been given distinctive captions. The files in which these libraries are found are named on
the appropriate pages.
FILES
/lib/libc.a
/lib/libm.a, /usr/lib/libm.a (one or the other)
SEE ALSO stdio(3), nm(1), ld(1), cc(1), f77(1), intro(2)DIAGNOSTICS
Functions in the math library (3M) may return conventional values when the function is undefined for the given arguments or when the value
is not representable. In these cases the external variable errno (see intro(2)) is set to the value EDOM or ERANGE. The values of EDOM
and ERANGE are defined in the include file <math.h>.
ASSEMBLER
In assembly language these functions may be accessed by simulating the C calling sequence. For example, ecvt(3) might be called this way:
setd
mov $sign,-(sp)
mov $decpt,-(sp)
mov ndigit,-(sp)
movf value,-(sp)
jsr pc,_ecvt
add $14.,sp
