BUT, pthreads/win32 is available from cygwin. It compiles with mingw or
msvc. To my mind, they have done a good job. Threading code that
Brickle wrote ran immediately under pthreads/win32. There is some
chance omnithreads would work using this.

Hi David,
No, we haven't tried connecting the two boards using cable. What do you mean

Heyo,
Eric, I think you started to mention something about this last night. But do we

several fields that we won't ever need to set on our end, only need to read.
For instance, the dropped packets field.

I am trying to install gr-wxgui for gnuradio, I run these commands but as

That makes sense. The envir

Sorry; I was unclear. Yes, if I put my laptop into 1Mbps mode then I can
see data packets. Even in 2Mbps mode (especially if I use the -p

Could you explain more precisely what you are doing, and what happens?
I have run the code under NetBSD with modified tap(4) driver that
handles 802.11 in addition to Ethernet. I am not clear on the state of
802.11 support in the Linux tap driver.

Hi,
I am using gnuradio with BBN's 802.11 mac in Ubuntu platform.
When I am using bbn_80211b_rx.py, I cannot capture any packet.
But, when I am transmitting using bbn_80211b_tx.py, I can capture all
the packets as transmitted by the transmitter.
Has anybody faced this problem?
Thanks and Regar
