The present package is a set of tools for working with USB-serial interface chips, specifically those FTDI and Silabs chips that are of relevance to FreeCalypso. The following tools are included: * Utilities for examining the non-volatile baud rate configuration on CP2102 adapters and for reprogramming their EEPROM, switching between "standard" 230400/460800/921600 and GSM-specific 203125/406250/812500 baud rates; * A utility for switching a FreeCalypso DUART28 adapter between C and S configurations, as well as checking the current configuration; * General-purpose FT2232x and FT232R EEPROM programming tools. The common theme across all of these tools is that they talk to a USB-interfaced chip at the native USB level, bypassing the usual abstraction of ttyUSB, and thus require libusb. More specifically, our tools are built on libusb-0.x API, consisting of <usb.h> include header and -lusb link library pull-in; on "modern" systems these pieces will typically be provided by libusb-compat-0.1 package wrapping around libusb-1.x, but in the spirit of Holy retrocomputing, really old systems can be used with native libusb-0.1.
