minimizing windbg messages

WINDBG
1

Hi,

Greetings.

I have just started using windbg and not sure in case something was set by
me else it is usual to see lots of messages but when I try some commands
during kernel debug, say “t”, I see the following clutter, which I do not
want:


kd> t

READ: Wait for ACK packet
PacketType=4, ByteCount=0, PacketId=80800001,
READ: Received correct ACK packet.
DbgKdContinue(10001,10001) returns 00000000
READ: Wait for type 7 packet
PacketType=7, ByteCount=f4, PacketId=80800001,
READ: Received Type 7 data packet with id = 80800001 successfully.

KdReadVirtual(80b95008, 8) returns 00000000, 8
kd> r

What are these messages and how do I get rid of these?

Thanks
