The serial_y_cable Tool

Usage

basic usage of serial_y_cable:

  ┌─────────────────┐                                                                     ┌────────────────────────────────┐
  │ hardware / DUT  ├──  hardware serial dev   ─────┬───────  virtual serial dev 0  ──────┤ application that controls      │
  └─────────────────┘      e.g.://dev/ttyUSB0       │          /tmp/ttyUSB0-V0            │ the hardware / DUT             │
                                                    │                                     └────────────────────────────────┘
                                                    │
                                                    │                                     ┌────────────────────────────────┐
                                                    └───────  virtual serial dev 1  ──────┤ serial terminal for monitoring │
                                                                /tmp/ttyUSB0-V0           │  - e.g. minicom, screen, etc.  │
                                                                                          └────────────────────────────────┘

Limitations

For now only monitoring on both virtual devices is implemented (bytes are only copied from the hardware side to the virtual devices).

Requirements

The following modules are needed for serial_y_cable

• pyserial
• key_stroke

You can install them easily from pypi.org:

pip install pyserial key_stroke
