IMHO, it's an order of magnitude easier to debug such problems in
user-space than in kernel/device space! Having "locks" in kernel space
means it's usually very very difficult to discover the exact state of
the system from user-space, and/or to forcefully change the state of the
system (i.e. much harder than simply removing a lock file). Fixing a
modem configuration is also usually easier than fixing a device driver,
at least for most folks.
Also IMHO, such things a ignoring modem control, or flow control, on a
port are hardware problems and should be fixed with appropriate hardware
solutions (i.e. jumpers in the connector!).
