[WriteLog] zero's or T's

[Jerry Ford]

Another question for the group.  I know I read this somewhere but I
can't seem to come up with it again so I'll put it to the gang.
In getting ready for this weekends NA Sprint!!
                      ( first CW test with Writelog )
I note that when sending serial numbers I am sending
" T "  in place of the zero.
There is a way to change this to zero but I don't remember where I
read that much less where I saw it.
So,  a little help please!!
How do I change it to " zero "??
Thanks Jerry               N0JRN
