Terminal software

We recommend the PuTTY software tool for connecting to S2C devices.
For connecting over Ethernet, you can also use netcat.
If you intend to use PuTTY to connect over Ethernet, please note: only the PuTTY installation you download from EvoLogics allows selecting the correct end-of-line marker.

PuTTY for Windows (patched)

EvoLogics open-source patch of PuTTY adds extra features to the software:

  • Change the End-of-line (EOL) character for Raw TCP connections:
    select between Line Feed (LF, \n), Carriage Return (CR, \r) or
    Carriage Return Line Feed (CRLF, \r\n) combination - so you can use PuTTY for TCP connections to EvoLogics modems

  • Upload/download files or directories over the serial port with ZMODEM protocol - useful for modems with firmware sandbox and serial interface

EviNS: Framework

Evologics intelligent Networking Software Framework (EviNS Framework) follows a paradigm of event-driven programming, each module is explicitly defined in form of pushdown automata and is driven purely by discrete events generated internally by event handles, by timers or externally by interface processors. The task of the interface processor is to provide the mechanism to receive and parse this data and pass it to the module. The task of the module is to handle this event, update the state and pass back to the interface processor tuples, to be converted to the appropriate format and delivered via the appropriate interface.
