Serial Port Pair is a virtual COM port pair simulating a nullmodem for Windows XP, Win Vista, Win 7 and Win 8.
There are x64 and w32 versions for Win Vista, Win 7 and Win 8. It is based on a
Microsoft VC++ sample. The driver framework UMDF 1.X is used for these operating
systems. Windows 8.1 introduces UMDF 2.0 but still includes 1.X.
[Only Windows 8]
The driver is unsigned. Win 8 can't install unsigned drivers with testsigning
turned off, which is the default, because of security reasons. Because the
driver isn't signed and should't look suspicious, its source is included in this binary package. You can compile it
with Visual Studio 2012 Professional (commercial) and Windows Driver Kit 8.0
To turn the installation of unsigned drivers on, process the following steps:
1. Open Control Panel
2. Open Update and Recovery
3. Choose Recovery
4. Choose Restart for Advanced startup
5. Choose Troobleshoot
6. Choose Advanced option
7. Choose Startup settings
8. Select Restart
9. After the restart disable driver signing enforcement with the F1...F12-keys
[Only Windows 8: end of instruction list]
The serial port pair can't transmit I/O requests, which start with a special
sequence, which is 31 byte long. This sequence is very unlikely and was introduced
to avoid using I/O control with large amounts of data. Install the serial port
pair server and the serial port pair client with the windows "add legacy hardware"
function (located in the device manager). The device manager can be accessed
in the control panel. You must select an item in the device list, if you want
to access the menu item for adding legacy hardware.
You can install only one port pair with the binaries. If you want more Pairs,
you must change device.h and recompile with Visual Studio Professional 2012
and Windows Driver Kit 8.0.
Find device.h in SolutionServer and SolutionClient. Find the following line:
DEFINE_GUID(GUID_DEVINTERFACE_COMPORTSERVER, 0x86e0d1e0L, 0x8089, 0x11d2, 0x9c, 0xe4, 0x08, 0x00, 0x3e, 0x30, 0x1f, 0x73);
DEFINE_GUID(GUID_DEVINTERFACE_COMPORTCLIENT, 0x86e0d1e0L, 0x8089, 0x11d1, 0x9c, 0xe4, 0x08, 0x00, 0x3e, 0x30, 0x1f, 0x73);
Change the number in both files. Both files must be equal. Recompile for your system
and install the driver package located in the output directory with the device
manager menu. You can install the server first or the client, it doesn't matter.
