	When I installed SCO UNIX SYS V/386 Rel 3.2.2 I had to tell
the modem to answer the phone by issueing some of the hayes commands.
I will list them here as they appear in my sysadm manual.


	AT&F		Fetches factory configuration
	ATT		is Tone dialing
	ATL0		is low speaker volume
	AT&D2		sets DTR "2": goes on hook when DTR drops
	AT&C1		Sets carrier detect (CD) to "1"
	ATS0=1		Answers the phone after 1 ring
	ATS2=128	disables the modem escape sequence
	ATE0		does not echo
	ATQ1		in quiet mode (does not answer with OK after this command)
	AT&W		Stores your settings in no volitle memory

Now I cannot garentee that this will work for your system but this was
neede to make my modem work with the operating system. I belive that 
all that you are doing with the enable command is setting up a getty
process to expect a login on that line (tty6). I have no idea what the
command is '/ect/modem'. If you store these settings in nonvolitle memory
with the modem and it does not work then all you have to do is
issue the command AT&F and AT&W and it will erase the configuration
that you just put in.

Please remember that this worked for **MY** modem. It may not work for
yours. I have a viva modem 24 external. Please check the modem manual
against the setting that where explained above.

hope this helps.
