1 | /* This program receives an rx01 image from the serial port from the PDP8 dump |
2 | program. It will prompt for the file to receive or use first command | |
3 | line argument. It needs a config file dumprest.cfg or $HOME/.dumprest.cfg | |
4 | with the format defined in config.c | |

6 | This program should be running before the PDP8 end is started. | |

8 | On the PC ctrl-break will terminate the program | |
