* "G1 X1 ; test" was not executing "G1 X1" due to never leaving comment mode.
* "M117 Hello \;)" printed "Hello \" to the display due to not replacing serial_char properly.
Tested with the following commands:
* M117 Hello ; test => displays "Hello" on display, ignores "test"
* G1 X1 ; foo => moves 1mm in X, ignores "foo"
* ; test => completely ignored, not even acknowledged
* M117 Hello \;) => displays "Hello ;)" on display
* M117 Hello \\;) => displays "Hello \" on display, ignores ")"

# Comments
|
|
|
|
Comments start at a `;` (semicolon) and end with the end of the line:
|
|
|
|
N3 T0*57 ; This is a comment
|
|
N4 G92 E0*67
|
|
; So is this
|
|
N5 G28*22
|
|
|
|
(example taken from the [RepRap wiki](http://reprap.org/wiki/Gcode#Comments))
|
|
|
|
If you need to use a literal `;` somewhere (for example within `M117`), you can escape semicolons with a `\`
|
|
(backslash):
|
|
|
|
M117 Hello \;)
|
|
|
|
`\` can also be used to escape `\` itself, if you need a literal `\` in front of a `;`:
|
|
|
|
M117 backslash: \\;and a comment
|
