SYNC I/O Serial Port & Com Port

[Tomio Broman]

I think I've posted this topic before but would like to give it a try again.
When using the Machine Control option, it seems to be that the Computer Com Port is not supported, or at least is not stable.

I go into Setup/Peripherals - Machine Control TAB.
When I use the Computer Com1 Port, I select Com1 - SONY 9pin - then it would totally freeze on me when I try to select a deck profile. Sometimes it would let me choose a deck, but if I ever have to go back in again to select another deck, it would freeze as soon as I click on the deck drop down list.

Everything is fine if I use the Serial port 1 on the SYNC I/O.

I can keep on with my work, but something just makes me want to find out why it doesn't work on the Computer Com port.

DIGI, is this a BUG? Will it be fixed in future updates?

I'm on a certified IBM Intellistation Z Pro 6221.
