I suspect your right - it does sound like a terminal I/O issue.

What is the $TERM variable on the remote system?  What is its value on
the local system (Mac).

When I've run into this problem, the cause has generally been that the
remote system doesn't recognise the term settings of the local system. 
Setting to vt100 or xterm often works, but if these settings are not
compatible with your local term settings, you can get weird behavior. 

I use to get this problem when logging in from a console on Linux to a
non-linux remote host. The remote host wouldn't recognise the Linux
console terminal name and depending on the system, would set the term to
'dumb' or something similar. I even had this problem when colour xterms
first came out because older unix boxes didn't understand a term type of
xterm-color. 

The three solutions I used were to 

1. Force a compatible term type by setting the TERM variable on the
remote system before starting emacs

2. Copy the terminal definition into the terminfo database on the remote
system

3. Setting my local TERM variable to something that is recognised by the
remote system. 

Note that I've not used windows since 3.11, so have no idea how all this
stuff interacts with windows. 

If your Mac term setting is something 'unusual' - particularly if its
something only recognised on Mac systems, either you need to find a
compatible term setting for the remote system or you need to change the
local system to something more 'standard'.

FAQ. Maybe check that out and see if it gives some hints. It comes
bundled with emacs and is available from the help menu
