freebcp - comma delimited output file

FreeTDS list:

I'm using the freebcp from the freetds-0.82-6.el6.x86_64 package and can't
seem to get the file to come out comma-delimited.  It ends up being
tab-delimited.

freebcp MYDB.dbo.DV_DEVICE_T out "/home/myaccount/test.csv" -c -T -t, -S
servername -I /etc/freetds.conf -U me -P `cat mssqlpw.txt`

What is problematic about my command syntax?  Is there a bug with the -t
parameter?

Thanks,
Tim
