Enables attaching layers (such as protocol analyzers) to sessions and logs.

TX Modifier allows you to alter the outbound packets of any non-read-only IO Ninja plugin in the following ways:

Add prefix
Add suffix
Re-transmit N times with a specified interval
Insert inter-character delays

When specifying prefixes and suffixes, you are free to use any of the C-escape characters — including the non-standard \e for the ESC character (ASCII code 1B) and \u for Unicode code points. That means, you can easily define arbitrary byte sequences, for instance: abc\r\ndef\x01ghi\u2122.

Getting Started

Step 1. Attach Layer

In any non-read-only IO Ninja session you want to modify the outbound (TX) packets of, e.g. TCP Connection or Serial, attach the "TX Modifier" layer via the "Layer Pipeline" dropdown.

Step 2. Set Modifications

In the "Control" pane, set your required prefix, suffix, interval, inter-char delay, and retransmit number. When specifying prefixes and suffixes, you are free to use any of the C-escape characters.

Step 3. See Modified Packets

All subsequent outbound (TX) packets will be sent based on your previously selected modifications. Send a packet from the log to confirm your packet is correct, and adjust if needed.
