1 | /* This program sends an rx01 image out the serial port to the PDP8 restore |
2 | program. It will prompt for the file to send 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 | |
5 | ||
6 | The PDP8 end should be running before this program is started | |
7 | ||
8 | On the PC ctrl-break will terminate the program | |
