gdbserver + serial link, status + runtime fix

["Korbel, Michal" <Michal dot Korbel at intel dot com>]

Hi,
GDBSERVER not work properly with serial link, the baudrate parameter is not
set.
I was add two lines in remote_open file in remote_utils.c file
and gdbserver work properly with 115200 baudrate:
	termios.c_cc[VMIN] = 1;
	termios.c_cc[VTIME] = 0;

	tcsetattr (remote_desc, TCSANOW, &termios);

+	cfsetospeed(&termios, B115200);
+	cfsetispeed(&termios, B115200);
      }
#endif

I think we need more serial link description:
for TCP/IP we use	gdbserver IP_ADDRESS:PORT_ID path/image
for serial link	gdbserver
/dev/ttyS?,speed,data_bits,parity_control,stop_bits path/image
when someone not write serial link parameter we can use dafault parameter:
115200,8,N,1

for first serial link with speed = 115200 with 8 data bits and no parity
control and 1 stop bits we can write:
"gdbserver /dev/ttyS0,115200,8,N,1 path/image" or "gdbserver /dev/ttyS0
path/image" when use defaults.

Below we have runtime fix for run gdbserver with serial link usage without
any changes:
1) We need properly configure serial link in any aplication (I was use
mincom),
2) Next we need start "gdbserver /dev/ttyS? <#image_path>/image" (/dev/ttyS?
meaning serial link ID).
3) When gdbserver start properly we need kill mincom aplication (NOT EXIT).

Hi,
The fix for 32-thread limit was done by Kevin Buettner in 2001-05-03.
You need try snapshot version after this date, or you can try
GDB 5.1 ( CVS TAG : gdb_5_1-2001-07-29-branchpoint ).

Hi, gdb had a 32-thread limit.  I heard that this
limit has been lifted in the current version in CVS. 
I tried the snapshot from Aug 8 and that limit still
seemed to be there.  Is there anything I need to do to
configure the recent gdb snapshots to support
debugging more than 32 threads?  Thanks for any info.
