smokeping invokes tcpping as:
/usr/local/scripts/tcpping -C -x 10 10.48.5.21 1521

Which gives me:
10.48.5.21 : - - - - - - - - - -

/usr/local/scripts/tcpping -x 10 10.48.5.21 1521
OTOH gives me:

seq 0: tcp response from 10.48.5.21 [open]  0.543 ms
seq 1: tcp response from 10.48.5.21 [open]  0.766 ms
seq 2: tcp response from 10.48.5.21 [open]  0.632 ms
seq 3: tcp response from 10.48.5.21 [open]  0.455 ms
seq 4: tcp response from 10.48.5.21 [open]  0.672 ms
seq 5: tcp response from 10.48.5.21 [open]  0.686 ms
seq 6: tcp response from 10.48.5.21 [open]  0.621 ms
seq 7: tcp response from 10.48.5.21 [open]  0.579 ms
seq 8: tcp response from 10.48.5.21 [open]  0.581 ms
...

Where "0.543 ms" which differs considerably from "-" in the former
output. ARRRRGH.

-C   print in the same format as fping's -C option

I found the bug. tcpping invokes tcptraceoute and the output format
differs, depending on whether you use an IP or a HOSTNAME as argument.
