arm-elf-gdb/Cygwin does not see /dev/com1

[Pierre Habraken]

Hello,

I am trying to connect arm-elf-gdb, running in Cygwin/w2k, to an
evaluation board (Evaluator7T) through a serial link.

Sending character strings (using cat) to /dev/com1 from the shell (bash)
works fine.
However launching gdb with the following commands fails :

$ arm-elf-gdb guirlande.exe
GNU gdb 5.2

This GDB was configured as "--host=i686-pc-cygwin --target=arm-elf"...
(gdb) set remotebaud 57600
(gdb) target rdi /dev/com1
Could not open device "/dev/com1"
(gdb)

How could I connect gdb to /dev/com1 using Cygwin ?
Thanks for any help.

Pierre

Does it work to use just "com1" (without the quotes)?

Wonderful, it does work (target rdi com1) !

Thanks a lot,

Pierre
