What happens if you press any key although there is no prompt?

Sonofa! I never thought to press enter ... when I did, it prompted for a password, so I just hit enter again and was immediately prompted for a user to login with. 

Can you test the serial connection from a client other than windows
+putty? Just to start discarding culprits...

No need now :D see above. Thanks for the obvious tip lol.

How ironic ... the power blinked and that machine rebooted, when it came back up, I saw it boot via the serial console, but it would freeze during the boot process w/ 

"Loading the saved-state of the serial devices..."

I then manually rebooted the box a few times and it always said the same thing, a few times though, it would print a few characters of garbage and then hang, no physical console access or serial access. The only way I got the machine to come back up was to unplug the serial cable from that box and it came back up normal ... now this isn't normal or wanted behavior and it needs to be adjusted.

BTW, I bumped it back up to 115200 (as that is the max speed of that card and the card in my windows machine, when I do connect via serial, it does work and quite well. I also updated my inittab from TO to use co, not sure if that made a difference but based on what I read, as long as it was unique, it didn't matter, co seemed more logical anyway. Now question, does Debian treat co special? Would there be issues or should I choose another two-letter abriviation such as se/SE/sc/SC for serial console? Only reason I point it out is because of my trouble getting console w/ keyboard and not serial....
