The target is sitting at the RedBoot prompt. I physically tapped the
serial line and watched from another host. The packet from GDB never
makes it to the wire. If I startup minicom on the host with GDB still
trying to connect, then data starts flowing on the wire again although
GDB and minicom are fighting over the read data.
