老工程師的練功坊

Full features list:

• Any number of virtual serial ports pairs can be created
• Virtual serial ports are absolutely the same copies of real ones - applications won't see the difference between real and virtual serial ports
• Virtual serial ports can be controlled directly from your own application via Dynamic Link Library supplied with VSPD (for OEM License owners)
• Link between virtual serial ports is much faster than real null-modem cable connection and solely depends on your processor speed (average transfer speed is about 5.5 Mbytes/sec)
• Real serial ports are not occupied - you can even have no real ports in system at all
• Strict baudrate emulation (for Windows NT4/2000/XP/2003/Server 2008/Vista/Windows 7)
• All signal lines are available: DTR/DSR/CTS/RTS/DCD/RI
• Full support of HandFlow control (Hardware and Xon/Xoff)
• Virtual serial line connection break emulation (for Windows NT4/2000/XP/2003/Vista/Server 2008/Windows 7)
• Different virtual null-modem schemes are available: standard/loopback/custom (for Windows NT4/2000/XP/2003/Vista/Server 2008/Windows 7)
• Virtual serial port may have any name you like, even the same name as real port has
• Ports are automatically re-created on system reboot (prior to user login)
• Possibility to change names of virtual serial ports, created by VSPD, shown in Device Manager
• Restriction of access to created virtual ports for various applications (for Windows 2000/XP/2003/Vista/Server 2008/Windows 7)
• Virtual Serial Port Driver and all of its internal drivers are digitally signed
• Complete information about current virtual serial port state, sent/received data, etc (for Windows NT4/2000/XP/2003/Vista/Server 2008/Windows 7)
• Windows kernel driver technology support (WDM, WMI, Power Management, PnP, etc)
• Printers can be assigned to any virtual serial port (available after Windows reboot)
• Hyper-threading and VMware friendly
• No reboot is required after VSPD installation, creation and reconfiguration of virtual serial ports

• 它能做什麼?

我主要都是用它來模擬兩台電腦 COM Port 之間的通訊。

在以往若是要開發兩台電腦之間的 COM Port 通訊，我們可能需要兩條實體Serial COM Port，然後對特殊角位跳線，用來模擬通訊以便開發相關軟體，自從我多年前知道有這東西，就沒跳過線了，今天特地來分享這個東西給其他人知道。

• 如何模擬COM Port之間的通訊?

當我們打開軟體後可以看到我們電腦的實體Serial COM Port

選擇First Port & Second Port

接下來我們就可以看到我們在電腦中已經有虛擬的 COM Port 了，就算這個軟體關掉也仍能保持虛擬 COM Port 的存在

可以觀察這個Port是被哪一隻程式所佔用，發送以及接收的 Bytes 狀況，由此可能得知自行開發的軟體有沒有正常在工作。

手動模擬斷線/復線

設定腳位跳線，雖然看起來是如此，但我改了設定也看不出什麼變化。

Full features list:

• Start/stop monitoring the serial port that is already opened by another application (available in Professional Edition only)
• Serial Port Monitor is completely compatible with Windows 7 /Vista (both x32 and x 64)
• Serial Port Monitor and all of its internal drivers are digitally signed
• Any number of serial ports can be monitored simultaneously
• Supports all COM-port types: standard on-board ports, extension board ports, software-based virtual COM ports, bluetooth serial ports, USB to SERIAL cradles, etc
• Data transmission monitoring and logging
• Advanced send dialog: easily send various types of data, apply aliases for faster typing and automation, send files and loop functions and commands, change serial port parameters on-the-fly (available in Professional Edition only)
• Real-time data capturing
• Various monitoring visualizers: table view, line view, dump view, terminal view
• Incoming and outgoing data streams logging
• Multi-colored commands display in table view
• Any software/hardware that works with a serial port can be monitored
• Intercept and record all serial input/output control codes (IOCTLs), tracking their full details and parameters
• Customizable monitoring session logging (several timestamp formats, different scale of notation, customizable logging string length etc.)
• Convenient and flexible monitoring session's management: saving and loading all monitored data, exporting and redirecting to file functions
• Monitoring session exporting (HTML, ASCII text, UNICODE text, Exсel CSV) and automatic redirection to file (Serial Port Monitor will automatically append all monitored data to a file in real-time)
• Supports copying all recorded data to clipboard
• Supports adding data automatically before and after packet to be transmitted
• Full duplex mode supported
• Control lines status visualized
• Unique stream filtering tools with presets
• All baudrates supported
• Flexible configuration: stopbits, flow control, parity control, data bits, highlighting, etc.
• User-friendly flexible interface: the software is designed to provide easy access to serial ports, no programming skills are required

• 它能做什麼?

我主要都是用它來觀察COM Port通訊的封包，瞭解封包的傳遞格式才能正確的處理資料。

• 如何觀察 COM Port 封包?

開啟軟體後，定義自己想要監視的Port

按下箭頭後，就可以看到封包的傳遞(好多攪…)

除了監視封包外，也能傳送封包，讓你輕易的調試相關設備。
