In response to the query concerning 40 Meg disks on the 7300, there is
a company called Bell Technologies in Fremont, Ca, which is marketing
a 40 Meg 1/2 height five and a quarter inch drive (unformatted - I believe
it's 31 Meg formatted) which they claim is 100% compatible. It has an
average access time of 85msec, and they're asking $2995 for it (EEK!).
They are also offering a $300 rebate on your original 10 Meg, and $600
for your original 20 Meg (assuming it's brand new), although I suspect this
marketing scheme is for a limited time only.

Personally, I think they're asking too much.

There are also rumors that AT&T-IS is currently negociating to make other
40 Megs availavle themselves, to be announced next quarter. I tend to
believe such rumors, as I noticed drivers for Atasi and Rodime 40 Meg drives
in the installation menus when I brought the system up. They are also 
supposedly going to make even larger drives available that don't fit in the
box, but sit in their own cabinet. I suspect they may be available cheaper
through AT&T then trying to by one directly yourself, but I suggest you
shop around in any case.

As to the fellow that was having trouble accessing his modem, you
must make sure that the phone line in question is configured to transfer
data, as opposed to voice communication. The current configuation should
appear on a status line at the top of the screen. If no status line appears,
you have not yet informed the system as to the nature of the telephone
hookup that you're using. Instructions for doing this should be found in
the Telephone Manager Manual.

Once the status line is present, the easiest way to switch between voice
and data mode is to position the mouse on the phone status indicator,
hit B1 on the mouse (which activates the Call Screen), and then the F3
button, |Line Select|. This should toggle you to the line configuration
you need (assuming a single line system). Then just exit the the Call Screen
and you should be ready to go.

Currently, I haven't been able to discover a means of toggling the
configuration of the voice/data mode from within a program. The ability to
do this is not documented, and AT&T support personnel haven't been much
help. This means you must use the method described above if you have a
single line system to toggle the modes manually. (If you have a two line
system, you could leave line two in data mode at all times.)

For those of you who want to use the cu program on a single line system,
you too must make sure you're in data mode. The command

cu -s 1200 -l /dev/ph0 5555555

will dial 555-5555 and attempt a 1200 baud connection through line one.

Hope this helps.
