Way Serial

I need a way to take the start of a serial signal into a pulse that ends once the signal stops.?

So I have a serial eeprom and I need to take the serial address signal to make a pulse that rises from low to high once the address signal starts and falls when it is done. Is there a simple way to do this? Thanks in advance!

you just OR the serial stream or trigger a latch

and a monostable times out when the data finishes

BUT what if the data is mostly low (0’s)
you wont see it start and you wont see it stop

That’s why they are other signals to say data is ready
and why there is a frame and a clock (or some similar arrangement)

The virtual serial ports. Virtual Null Modem Cable.
There are two applications that exchange data via serial ports. These programs should be connected and a null-modem cable is used to it.
There are several problems you may come across:
• There are two serial ports on your PC.
• All serial ports are already occupied.
• Need to connect several pairs of programs simultaneously and one null-modem cable is not enough.
Is there a way out of this?
Yes, there is. Virtual Serial Port Kit by FabulaTech can emulate unlimited number of serial ports and connect each pair of them via a virtual null-modem cable.
So, your applications can exchange data just as they do through serial ports and null real hardware modem cables.
For example, using Virtual Serial Port Kit you can create pair virtual serial ports (eg COM7 and COM8) and connect two applications to them. All data that the first application writes to COM7 is read from COM8 by the second application, and vice versa.
An example of working with Virtual Serial Port Kit
It is easy to prove. You can run two copies of the terminal program (eg HyperTerminal rule Windows) and connect them to COM7 and COM8.
Therefore, everything you write in the HyperTerminal will appear first in the second and vice versa. You can also transfer files between HyperTerminals and do whatever you want.
Maximum Benefits
• applications recognize virtual serial ports created by VSPK as standard serial ports hardware.
• No need to spend money on different null modem cables, because VSPK emulates all types of null modem systems.
• Its ports number of hardware are not occupied. To be used for other purposes.
• These are no cables hanging in the back of your PC, because all transmission Data is being done inside.

Who can Virtual Serial Port Kit is used?
Virtual Serial Port Kit is ideally suited for developers software series. Accelerates the development process during debugging and data recording period. You can debug the program (using the serial port) by connecting another program (eg serial device emulator).
Virtual Serial Port Kit will meet all possible needs and requirements.
