output pipe at "~./simnow/comX/simnow_in " and
" ~./simnow/comX/simnow_out ". External applications should read data from the
simulation using the simnow_out named-pipe. Conversely, external applications should
send serial data to the simulation using the simnow_in pipe.
Note that it is not possible for two simualtor sessions to communicate with each other on
the same host using named-pipes. This is an issue that will be fixed in a future version of
the simulator.
When the simaultor serial port has been configuired to use the host serial port, the
simualtor will open "
/dev/ttyS0 " or " /dev/ttyS1 " (depending on wether it is COM1
or COM2). Note that the user will need to be running the simulator with root privelages
to avoid an access denied error when the simualtor attempts to open the device. The
simulator can communicate with external applications, such as a kernel debugger in this
mode.
