data transmission

The blog article delves into using the Linux `dd` command for managing input/output operations on serial ports like `/dev/ttyUSB0`. Originally for data copying and conversion, `dd` can efficiently handle reading from and writing to serial devices once they are configured using `stty` for specific settings such as baud rate and parity. It includes commands for setting up and executing these operations, with additional examples for continuous reading and file transfers to a serial device, underscoring `dd`'s versatility in direct hardware interactions.

This blog article explains using the `curl` command-line tool to bypass proxy settings with the `--socks5-hostname` option. This approach directs requests through a SOCKS5 proxy, resolving hostnames at the proxy, unlike `--socks5` which resolves locally. Useful for avoiding restrictive proxies or testing server connections directly, it enhances control without altering global settings. An example and script demonstrate this method's application.
