I believe the reason for this is the same reason that you can't hook a modem to your console port. The "Ready-To-Send", and "Clear-To-Send" signals don't exist on the console port, thus, no flow control. This is the big physical difference between the console and aux port; the aux port provides "RTS/CTS" signaling. If you tell your terminal to throttle data based on these signals (which it never receives because the console isn't providing them) it gets confused.

Don't know the reason, my co-worker said he found some link on CCO about it.
