- I'm curious about one detail of the FAX modem implementation. For outbound
- calls (sending faxes) the local computer obviously knows whether it's sending
- a fax or sending data, and so can put the modem in the appropriate mode before
- making the call.
-
- However, for inbound calls... Suppose I connect one of these modems to my VMS
- or Unix system. If the modem gets a call from a data modem, I want this to be
- routed to a login process on my machine, so that the remote user (or uucp host,
- or whatever) can log in and do work. But if it gets a call from a FAX modem,
- this won't work. No way is the remote FAX going to know how to log in to my
- machine.
-
- I can see it working for FAX if I set up a serial port on my machine as a
- "dedicated FAX data" port, with a FAX receiver process always listening on that
- port... but if the modem is connected to that port, the modem can't be used for
- data calls.
-
- How does Telebit address this???
