Yeah. "Strike that: reverse it."

The difficulty is that it is possible to embed such an oddball setting
in the ATZ restored configurations that HylaFAX would have
considerable difficulty restoring it.

Strange locked down data terminal speeds and settings and other
oddnesses that can prevent HylaFAX from actually communicating with
the modem without a restoration to more standard settings. I'm not
saying it's likely, just possible.

ModemFlowControl is present in the "skel" file, which I thought
was parsed at runtime. Apparently not!
