GDB 5.2, NetBSD 3.0, serial connection [/dev/dty00] failure

I am hoping for some guidance to help troubleshoot a serial connection
failure using arm-elf-gdb 5.2, running on NetBSD 3.0:
This GDB was configured as "--host=i386-unknown-netbsdelf3.0
--target=arm-elf".
We have an Atmel eval board [EB40A] connected via a serial cable running
Angel. We are able to communicate with the board using "tip -9600 dty0"
and also using minicom, configured to /dev/dty00. However, when we
attempt to connect with the board using GDB we see:
(gdb) set remotebaud 9600
(gdb) target rdi /dev/dty00
Could not open device "/dev/dty00"
...since we are able to talk to the board using both tip and minicom,
this seems to be specific to GDB. Any suggestions would be appreciated.
Thank you,
