OSCAR 13/40 Telemetry Software for Linux

phase3.tar.gz was last updated Jan. 10, 2001. It contains the following
programs: 

phase3 [--no-crc] device 
       reads blocks of 512 bytes plus 2 CRC bytes from the specified serial
       device at 1200 Baud. If the --no-crc option is given, phase3 assumes that
       the CRC bytes are discarded by the receiver and thus expects blocks of 
       only 512 bytes. All received blocks are written to stdout (CRC not 
       included). If there was a CRC error, bit 7 of byte 0 is set to 1. If the 
       --no-crc option is given, bit 7 of bytes 0 and 1 is set to 1. Information
       messages are written to stderr. 

phase3c 
       reads OSCAR 13 telemetry blocks from stdin, converts them into a
       human-readable format and writes them to stdout. 

phase3d 
       same as phase3c, but for OSCAR 40. 

sendtlm 
       very experimental, soundcard-based telemetry transmitter, imitating
       the laser transmitter of OSCAR 40. 

tlmfilter mask value 
       a very primitive telemetry block filter. 

Some additional notes about phase3: If you have a DSP-12 or an old G3RUH
modem, you have to specify --no-crc. You also must make sure that the DSP-12
does not send a carriage return after column 80 and that it does not append a 
linefeed after a carriage return (Main Menu - Setup Menu - Configure Serial 
Port Parameters). 

There is no additional documentation, but the sources are very small and
easy to understand.
