💖 DRS232(1) — the drs232 girlies' manual 💖

okay so bestie, welcome to drs232, a little icon from the User commands section. she does Horus SSTV reception using the codec2 library, and she is lowkey obsessed with finding her unique word. iykyk 💅

✨ SYNOPSIS ✨

drs232 usage: InputOneBitPerChar OutputPacket [-v[v]]

that's it. that's the whole vibe check. 🫶

🌸 DESCRIPTION 🌸

so the way this works is: drs232 is out here looking for a unique word in a series of bits. and when she finds it?? she deframes a RS232 encoded frame of bytes. periodt. that's the whole job.

she's used for high bit rate Horus SSTV reception, which is giving main character energy fr fr. 🔥

okay now the part you actually need, the frame format, look:

16 bytes 0x55 - 0xabcdef01 UW - 256 bytes of payload - 2 bytes CRC

so: 16 bytes of 0x55, then the unique word 0xabcdef01, then 256 bytes of payload, then 2 bytes of CRC. iconic layout honestly. 👑

and each byte is encoded as a 10 bit RS232 serial word, like this:

0 LSB .... MSB 1

so it's a 0, then the bits from LSB up to MSB, then a 1. that's the whole sandwich bestie. 🥪

🎀 OPTIONS 🎀

  • InputOneBitPerChar (first argument) — this is the file name of a file with Horus encoded bits. and if you pass - instead? she takes the input from stdin. slay. ✨
  • OutputPackets (second argument) — the file name of a file to be created with modem sample data. and if you pass - here? the output gets sent to stdout instead. 🦋
  • [-v] [-vv] (optional third argument) — sets the verbosity of the output. -v for a lil chatty, -vv for fully unhinged. no cap. 💬

👀 SEE ALSO 👀

go give these sisters some love too, they're all part of the fam:

bestie reminder: the input/output arguments are literal file names, and - means stdin / stdout. don't get it twisted. 💀

k bye, ily, go deframe something 💜
