4D does have some procedures to talk to the modem port.
(They don't help in this case, however...)

In the past, this was because Tops implemented record locking in a way which
is incompatible with the way Apple does it.

For this, 4D looks like the wrong solution.

Also, screen access should be significantly slower than shipping the raw data
over the line. You'd also tie up one mac per remote user, which is
prohibitively expensive.

What I would use is a mac or two with Liaison, and/or a bridge which can be
connected to a modem (NetBridge, whatever). Use this to access a file server.
(AppleShare-compatible. If you wait a few more months you can use
FileShare from System 7.0.)
Anything below a 9600 Baud V.32 modem is not a good idea -- file server
access is impossibly slow with 2400 baud.
