The Format of the F8 Output String

The factory setting for the output string format is as follows:
<SOH>DDD:HH:MM:SSQ<CR><LF>
where:
= ASCII Start-of-Heading character
<SOH>
= ASCII Carriage Return character
<CR>
= ASCII Line Feed character
<LF>
= day-of-year.
DDD
= hours.
HH
= minutes.
MM
= seconds.
SS
= milliseconds.
mmm
= colon separator.
:
= time quality character (see the following table)
Q
The time quality character, "Q", is one of the following characters:
SPACE = Time error is less than time quality flag 1's threshold
. = Time error has exceeded time quality flag 1's threshold
* = Time error has exceeded time quality flag 2's threshold
# = Time error has exceeded time quality flag 3's threshold
? = Time error has exceeded time quality flag 4's threshold
or a reference source is unavailable
The time quality characters can not be modified.
