Under cygwin(winxp), I can't access the com1(com2)


all,hello!

	 I can't use Insight(gdb) connect to redboot under cygwin. I can do this Under Linux. So I think it's the cygwin's
problem. At beginning ,I use cygwin 2.0, when set some gdb's parameter,such as :
 	set remotebaud 115200
	set  debug remote 1
	target remote com1
Then ,the gdb (insight) is dead! There is nothing after the command.
Then , I downloaded the recent cygwin and do it as above , there is a message after the command "target remote com1":
Inappropriate ioctl for device

My OS is windowXP2002, and the gdb(insight) is the one downloaded from the ecoscentric.com.
What's wrong?
Thanks in advance

            Regards
