Q. What can program do?
A. Smart Sniffer is placed between any YOUR soft and hardware. So it can do record of conversation between any other program and hardware. It can’t “talk” directly to hardware or “listen” it. However, if you need to do Input/Output into device just use SmartViewer and new scripting engine.
Q.What for this program can be used?
A.This program can be used for:
- Developing or implementing Serial (COM, USB) & Parallel Protocols
- Reverse-engineering the Serial & Parallel Protocols
- Developing Serial and Parallel Device Drivers
- Developing Hardware with RS232 interfaces
- Testing Software
- Testing Hardware
- “Black-box” researching.
- Even play games inside powerfull scripting engine.

Q. Is it free?
A. Yep. Starting from version 5 it is free-to-use.
Q. What are limits?
A. No limits any more. If you got one old – please let us know and we will fix it.
Q. What is “Stealth Mode”?
A. In this mode program will change randomly all internal specific values. So Sniffer cannot be detected by other software. The intensity of Stealth is picked up automatically by Sniffer depending on limitations of your current system.
However, some programs may check memory for the file names, we suggest you will rename SmartSniffer.exe manually to complete Stealth. Also close help file(s) and MPSLViewer(s) because it has references to Smart Sniffer and can be detected.
Q. Have I to have Internet connection?
A. Not any more. However you may want to run Online-Updater to have fresh bug-fixes.
Q. I got log and i want to send part of it into device.
A. Use SmartViewer. You can write own script or use Terminal.
Q. I’m not sure how to use Smart Sniffer…
A. Just remember to press F1 on keyboard when you don’t know what to do 
Q. What for “Insert bookmark” link?
A. While record is going you can click it and sequentially numbered mark will be inserted into log immediately. Later you will see all marks in log watching it by MPSLViewer, so it is convenient way to mark-up what was done between recorded packets.
Marks are available starting from v 3.2.1 of SmartSniffer. Minimal MPSLViewer’s version which supports it is 2.5.1.
Q. Sniffer hungs trying to log COM-mapped IR port. How to do?
A. IR-drivers are modern WDM and cannot properly restart in request of sniffer sometimes because sniffer uses NT4-compatible driver. Try next: put IR device in “visible” zone, when icon will appear in system-tray immediately press “Start” in sniffer.
