# drs232(1)

Horus SSTV reception using the codec2 library.

## NAME

drs232 - Horus SSTV reception using the codec2 library.

## SYNOPSIS

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

## DESCRIPTION

Looks for a unique word in series of bits.  When found, deframes a RS232 encoded frame of bytes.  Used for high bit rate Horus SSTV reception.

  Frame format:

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

  Each byte is encoded as a 10 bit RS232 serial word:

    0 LSB .... MSB 1

## OPTIONS

The first argument,  *InputOneBitPerChar* is the file name of a file with Horus encoded bits. If "-" is given the input is taken from stdin.

The second argument,  *OutputPackets* is the file name of a file to be created with modem sample data. If "-" is given the output is sent to stdout.

The optional third argument, *\[-v\]* *\[-vv\]* set the verbosity of the output.
