Reply to "LEGACY System Utility v1.0"

I have both the DCS base and a TTL-serial converter simultaneously connected to the Legacy base via the Legacy Y-cable; both devices seem to transmit to the Legacy base fine.

In theory, you could work with both connected if you used a "diode or gate": use diodes to prevent each device form pulling the line up when idle. Then you'd have to have a weak pull-up to 12V (5V for original TMCC base) to hold the line inactive (high) when neither computer nor ASC was transmitting.

Perhaps the Legacy Y-cable or the MTH DCS cable has some of this voodoo to make things work.
