SeriAllPort is a simple UI-based application for inspecting and analyzing data transmissions between a PC and serial devices (e.g., UART, RS-232/422/485).

• Operating Systems: Windows 10, Windows 11
• .NET: .NET 8.0 (LTS)
• UI Framework: WPF

• Support known CRCs from Catalogue of parametrised CRC algorithms
  

• Send raw bytes represented in hexadecimal format.
  Example: AA BB 11 22
• Send plain text encoded in UTF-8.
  Example: text

• Each button is linked to a predefined command, enabling fast and intuitive interaction with your devices.
  

When data is received, it may be displayed across multiple lines if the application does not understand the device’s protocol. For example, a stream like 00 AA 02 DD DD CC CC 00 AA 02 DD DD CC CC might appear as:

Received: 00 AA 02 DD DD CC CC 00 AA
Received: 02 DD DD CC CC

The Protocol System allows you to define how SeriAllPort parses the incoming data stream into packets, making the data easier to interpret.

Received: 00 AA 02 DD DD CC CC
Received: 00 AA 02 DD DD CC CC

1. Length Field

Use a length field to specify the length of the packet. For example:

[Length of Data][Data]

2. End of Packet Symbol

Specify a termination character or sequence (e.g., CR, LF, CRLF) to mark the end of a packet. For example, if the End of Packet Symbol is 0D 0A:

Data stream: 31 32 0D 0A 33 34 0D 0A

Received: 31 32 0D 0A // first packet
Received: 33 34 0D 0A // second packet

3. Timeout

Use a timeout to separate packets when the connected device does not use any kind of explicit packet boundaries. If there is no incoming data for the specified time, SeriAllPort treats the received bytes as one packet.

Example: Idle Timeout: 50 ms

Data stream: 31 32 0D 0A [idle for 100 ms] 33 34 0D 0A

Received: 31 32 0D 0A // first packet
// idle for 100 ms
Received: 33 34 0D 0A // second packet

• Preamble
  Optional. If defined, SeriAllPort scans for the preamble as the start of a packet. Bytes between the end of the last packet and the next valid preamble are marked as errors (R.Error).

  • Must be Fixed Data field.
  • Must be the first field.

• Fields
  User-defined fields within the packet.

• Length Fields

• Error Detection Fields

  • CRC
  • Checksum
  • XOR

• End of Packet
  Defines a termination symbol for packets.

  • Required if Packet Mode is End of Packet Symbol.
  • Must be the last field.
  • Cannot be used in Timeout mode.

• Fixed Length
  The length is defined and SeriAllPort extracts data accordingly.

• Fixed Data
  Both length and content must match the specified value.
  Example: Preamble and End of Packet are Fixed Data fields.

• Variable Length
  The length is determined dynamically by other fields in the packet.

SeriAllPort allows you to save your configuration as a Profile, making it easy to switch between different device setups.

A profile can include:

• Used Protocol
• User defined command buttons
• COM Port settings
• Preferred data display format
• Default send mode: raw bytes or plain text
