use: "target remote com1"
There appears to be an intermittent problem manifesting
this problem with a Cygwin Win2000 Insight-GDB host
setup. Usually resetting the target (maybe a few times) and
starting GDB clears this.

What is "COM1"? :)
On linux you can specify the serial port by:
(gdb) target extended-remote /dev/ttyS0
In other words, you have to type this at the (gdb) command prompt. If you
select the target from within the Insight gui as Remote/Serial (or ARM
Serial), you'll see these packet errors on Linux too (at least I did).
I just found out how to do this today -- I'm finally moving my code to a
real target... The way I found out how to do this was by:
(gdb) help target
With the arm-elf-gdb I have (Insight 5.2), there are several choices for
serial ports. I tried them all until I found one that worked. Chances are
there may be a better (or at least better preferred) way.
