tag list help

[enjoyfate]

hi, guys
I want to list all the tags ,how to do that?
For example I want to list  all the gcc cvs tags. After known  this ,
I could select a special tag to check out. Read the cvs manual, I
found it that cvs history seems to be useful.But when I try ,has
nothing to out put.

address@hidden ~/linux/lxr/test $  cvs -d :pserver:address@hidden:/cvs/gcc
history -T -a
No records selected.
address@hidden ~/linux/lxr/test $  cvs -d :pserver:address@hidden:/cvs/gcc
history -T
No records selected.

Any help is greatly appreciated! Thanks!
