[Tinyos-help] java hardware_check results in Node transmission

I'm using a mica2dot on a MB510 with Cygwin on the PC. I can download and
run a Blink program to blink the mote's LED, but 'java hardware_check'
results in a 'resynchronising' message and 'Node transmission failure'.
Here's the command sequence:
 cd /opt/tinyos-1.x/apps/MicaHWVerify
 PFLAGS=-DCC1K_MANUAL_FREQ=CC1K_915_998_MHZ make mica2dot
 MIB510=/dev/ttyS0 make reinstall mica2dot
 make -f jmakefile
 MOTECOM=serial at COM1:19200 java hardware_check
MOTECOM=serial at COM1:mica2dot java hardware_check
Step 2 gives the warning about the serial ID since this is for a mica2dot.
This group mentioned, last October, that this is OK and that hardware
verification will just report F's for the ID. The download in step 3 works
but when the mote's program runs, the LED turns on for a second and then
turns off - I expected it to blink instead. In step 5, I then get this:
Hardware check started
serial at COM1:19200: resynchronising
(pause, here, for roughly 15 seconds)
Node transmission failure
During the pause, when I sniff the serial line between the PC and the MB510,
I can see about 10 packets being sent and something being received as
sent: 7E 41 0E FF FF 20 7D 5D 02 0C 2C 81 66 7E
rcvd: 7E 40 0E 02 EC 7E
So the PC is getting a response that roughly correlates with the command
which implies that the port and baud rate is OK. Each command/response
sequence is slightly different, presumably due to a sequence ID - I'm not
 Should I be concerned that the LED isn't blinking?
 Any ideas why the test isn't passing?
Meanwhile, I'll try sending "hello world" from the mote to the PC and see if
HyperTerm can see it.
