Binary data transfer over a DL11 console fails.

codesleuth7 commented 9 months ago

The DL11 serial console device is not binary safe, and will not for example transmit a DEL (0x7F) character. Best fix for this would involve better console serial hardware. The software fix included that converts the binary to Base64 requires conversion back to binary after the transfer using a base64 utility. This fix also has the side effect of making the painfully slow transfer over a serial port take that much longer.
