Safe open

[yakir12]

Is there some way I can open a port (i.e. "/dev/ttyACM0") "safely"? Alternatively, test to see if a port is already open? Currently I can only do:

isopen(sp)

but this only works for a SerialPort type, that has already been opened before (and maybe closed at some point). My point is, if you don't know what ports are available, open, or closed, you can only start from get_port_list(), which gives you a list of strings. How can I, from that point, safely test if a port is already open, so I'll know to close it before attempting to open it again?

Never mind, I dunno how I missed that LibSerialPort.open(port::String) when that port is already open does not error. Sorry for the noise.

Never Never mind, forgot about the baudrate... Still a problem (for me).
