Tracing an interrupt-based program
Posted on 1998-03-19
I don't know where I should put this question in. I chose here anyway....
Hi, everyone. I have a problem for you concerning a set of
Its particulars are as follows:
1. it contains a driver (written in C) which alters a high
interrupt vector (i.e. driver.exe) and the main code is in here.
int_60h_entry proc near
get_string proc near <--- this part is where I want to know of.
2. A calling program (i.e 1.exe) calls the interrupt vector
mov ax, 0ah
int 60h <--- the debugger traces over this point
add sp, 4
p.s: there is an interrupt entry point in the driver, in which there are
cores and guts that I want to know of.
What I would like to do with these programs is:
Using Turbo Debugger 5.0 to trace into the interrupt, but debugger
only traces up to the point where it calls the interrupt (e.g. int 60h).
Then it steps over it.
Do you guys know how to trace into the interrupt?
,from the calling program to the driver?
