Incorrect command syntax appears to produce an "OK" response

robotd log:

: Sending to servo assembly: b'@6311 gpio-read -17\n'
: Got back from servo: b'# @6311 gpio-read -17\n'
: Got back from servo: b'@6311 + OK\r\n'

The following are excerpts of the Arduino's serial output stream as commands are manually typed into its input stream. Since the Arduino echoes every command it receives as a comment line, it is not necessary to show the input stream as well.

False positive responses seem to occur when the command string is too long:

# @1 gpio-read foo
@1 - 
# @1 gpio-read foob
@1 - 
# @1 gpio-read fooba
@1 - 
# @1 gpio-read foobar
@1 + OK
# @1 gpio-read foobarr
@1 + OK

Sometimes it corrupts all following commands with valid command names:

# @1 gpio-read f
@1 - 
# @1 gpio-read f
@1 - 
# @1 gpio-read foobarr
@1 + OK
# @1 gpio-read f
@1 + OK
# @1 gpio-read f
@1 + OK

But not always:

# @1 gpio-read f
@1 - 
# @1 gpio-read f
@1 - 
# @1 gpio-read foobar
@1 + OK
# @1 gpio-read f
@1 - 
# @1 gpio-read 1
@1 - 
# @1 gpio-read
@1 + OK
# @1 gpio-read f
@1 - 

It's not limited to just arguments:

# @1 gpio-read foo
@1 - 
# @10 gpio-read foo
@10 - 
# @100 gpio-read foo
@100 - 
# @1000 gpio-read foo
@1000 - 
# @10000 gpio-read foo
@10000 + OK
# @1000 gpio-read foo
@1000 + OK
# @1 gpio-read foo
@1 + OK
