This isn't arduino related, but if I asked this on a computer forum, I'd get a bunch of blank stares.
If I took a device running on COM/Serial, make a breakout board for the socket, had one computer be the "master" (gets all 9 pins), and one be a "slave computer" (only gets TX, RX, and ground), would it be possible to share that one device to the 2 computers with successful data transmission?
The device is a weather station, which has software on the computer. But for a special case, 2 computers need to be running that software for 1 device.
The only conflict I can come up with, is that if they sent signals asynchronously to the station, and got the asynchronous signals back, what if one computer's transmit overlapped the other's? They both need to be able to transmit, as the software 'pings' the device every so often.
Thanks. (and hopefully that made half sense)
