The modem syncs to the speed of the port ok, but the results are exactly the
same as before. Here is the output:
achilles# cu -l cuaa0 -s 9600
Connected.

This one doesn't even get the O of OK. What's more, just as before, no
output gets back from the tty unless there is a keystroke to prompt it. In
this case I am using the enter key to get the output character by character.
It seems that it requires any keystroke though, just to get the same effect.
I'm assuming this isn't necessary for your modem? I.e., it's part of the
problem, not a feature.
I don't think this is an indication of any problem the modem is having, just
that there is something which prevents the outout coming back cleanly.
Things like minicom and seyon are working fine without the output coming
back. Once a connection is established with an ISP data seems to flow ok
back from the ISP.
Any ideas?
Cheers,
Jon
