I am having no success with the serial tests - here is what I do
ser_filter -t 9000 /dev/ttyS0 - runs the filter, waits for a connection
arm-eabi-gdb-nw intsall/tests/io/serial/v3_0/tests/serial3 - gives me the
gdb prompt
target remote localhost:9000 - gdb says debugging using localhost:9000 and
returns to the gdb prompt
type 'c' - gdb says 'continuing' - then nothing else happens

What am I missing?
