22 | A debug packet whose contents are <data> | |
23 | is encapsulated for transmission in the form: | |
24 | ||
25 | $ <data> # CSUM1 CSUM2 | |
26 | ||
27 | <data> must be ASCII alphanumeric and cannot include characters | |
28 | '$' or '#' | |
29 | ||
30 | CSUM1 and CSUM2 are ascii hex representation of an 8-bit | |
31 | checksum of <data>, the most significant nibble is sent first. | |
32 | the hex digits 0-9,a-f are used. | |
33 | ||
34 | Receiver responds with: | |
35 | ||
36 | + - if CSUM is correct and ready for next packet | |
37 | - - if CSUM is incorrect | |
38 | ||
39 | <data> is as follows: | |
