BEST CHOICE TO VIRTUAL SERIAL PORT
SUDT SerialNull is an advanced configuration utility, which
purpose is to emulate RS232 serial ports connected via
virtual null-modem cable using Virtual Serial Ports Driver,
with SerialNull you can create any number of pure virtual
serial ports in your system connected into pairs via virtual
null-modem cable without having real serial ports occupied.
Virtual Serial Ports appear to operating system or any
Windows application as "standard" hardware serial ports.
Virtual serial ports created by SerialNull work exactly the
same as real ports in your system managing all signal lines
and emulating baud rate.

Why do I need SerialNull ?
There is an endless variety or reasons why you may need
additional virtual serial ports created in your system. Serial port data capture, telecommunication and data transmission
system, system debugging etc among them. On the other hand
you might need to establish serial port connection to
computer or device that has serial port that cannot be
connected with null-modem cable directly due to remote
location. In this case you may create application that uses
Virtual Serial Port Driver to communicate with remote serial
port by TCP/IP stack.
You may use Virtual Serial Ports for:
- Testing/debugging different
applications that use null-modem cable such as:
- any existing terminal
application
- your own application that
uses serial port.
For instance: you write your own program that
connects to modem and sends AT commands. In this
case you may emulate connection by creating virtual
serial port and send/receive commands to it.
Debugging on the real device is quite cumbersome,
slow and which is more important - it doesn't
support multiple-threading.
- you may want to create your
own data sniffer application that works with serial
port. In order to test or debug it you may create
virtual serial port pair.
- Testing/debugging different
serial port device emulators such as modems, fax, GPS
etc
- Testing/debugging firmware or
device drivers. You may even don't have this hardware in
order to develop the driver for it.
- Testing/debugging two
applications that have different address space and have
no direct way to contact each other.
- Testing/debugging application
for interception caching/proxying (as well as
translation, logging) data sent over network
Usually you need second computer or expansion card to be
able to perform such tests, however using SerialNull you may do
it on single computer using virtual port pair. |
Features list:
- Virtual Serial Ports are absolutely the same copies of real
ones
- Real serial ports are not occupied
- Full support of HandFlow control (Hardware/(Xon/Xoff)) etc
- High-speed transfer, Link between virtual serial ports is
much faster than real null-modem cable connection
- You can create as many virtual serial ports pairs as you
want
- Virtual link is much more reliable than common physical link
- Uses Windows kernel driver technology (supporting WDM, WMI,
Power Management, PnP, etc.)
- "Hot" installation - no reboot required after installation,
creation or reconfiguration of virtual serial ports
- User friendly GUI and on-the-fly help. It is very easy to
configure virtual serial ports pair
