I buy three NoName modems and put them on /dev/ttyS[234].  A few months
later I have seen the light :-) and so I buy two XyXEL modems and put
them on /dev/ttyS[56].  Soon afterwards a fourth NoName that was on
another computer becomes redundant there and so I put it on /dev/ttyS7.

Because the modems differ both in their defaults and in the functions of
similarly-numbered S registers, as well as the available AT commands,
compiling in the init string is perhaps not such a terrific idea in these
circumstances.  AT&F is not particularly the issue, as has been pointed
out: what you need to do afterwards differs too. 

After adding the modems to S4 and S5 you enter these commands:

		kermit -l /dev/ttyS4 NoName.k
		kermit -l /dev/ttyS5 XyXEL.k

(An example Kermit script to set up the modem for mgetty is appended to 
this note.)

I don't think you would do this.  You would set the NVRAM for mgetty, 
which, after all, is sitting on the line all the time.  You configure
your dial-out program to make whatever changes it needs to the defaults,
and it makes no difference whether they are the factory defaults or those
that you stored in NVRAM.  You wouldn't allow every comms program you run 
to write to the NVRAM.

Yes, there may be modems that do some highly irrelevant and eccentric
thing when you say "ATZ".  I don't think I would base an argument as to
whether to load factory defaults or custom defaults on such cases, nor on
the problems of broken comms programs.
