3.3.5 Target serial I/O via BDI
A RS232 port of the target can be connected to the RS232 port of the BDI2000. This way it is possible
to access the target’s serial I/O via a TCP/IP channel. For example, you can connect a Telnet session
to the appropriate BDI2000 port. Connecting GDB to a GDB server (stub) running on the target
should also be possible.
The configuration parameter "SIO" is used to enable this serial I/O routing.
The BDI asserts RTS and DTR when a TCP connection is established.
[TARGET]
....
SIO 7 9600 ;Enable SIO via TCP port 7 at 9600 baud
Warning!!!
Once SIO is enabled, connecting with the setup tool to update the firmware will fail. In this case either
disable SIO first or disconnect the BDI from the LAN while updating the firmware.
