Yes they do, seemingly.  It would seem that many of the various client 
utilities and such that come with HylaFAX were not developed in 
parallel, but rather in a method somewhat distinct from each other.  I'm 
not sure that bringing everything into agreement with each other is 
warranted yet, however.

Yes, both sendfax -t and -T are maximums.  Thus when either is reached 
the job is done.

It's possible to do, yes, but faxalter does not come with this 
capability.  (I could add the feature to hylafax+, but then you still 
wouldn't get it, hrmm... dilemma.)

Yes, these control the maximum number of calls that will be placed.

In order to prevent a T.30 incompatibility from racking up 12 phone 
calls there is this "tries" maximum that involves how many times a call 
connected with a remote fax device and properly initiated fax protocol, 
but then broke down on a certain page.  (This should almost never 
happen, by the way, and the fact that it is occcuring is indicative of 
there being more serious underlying issues.)

Well, the config change didn't cause this.  I'm not certain, either what 
would cause "ERROATH0R" ... is there another process (another faxgetty, 
maybe) toying with the same modem?

Technically no, not for sending.  But you've got some weird stuff going 
on there.

No \0727 is correct.  You can also write it:

Class1SwitchingCmd:     "<delay:7>"
