If it's a text (ASCII) file, there is no way to tell if the file is completely transferred unless the customer provides a separate checksum file of some sort (i.e. a file specifying the file's size, contents, etc.) or if you can determine completeness based on the file contents (e.g., the last line of the file contains "EOF" or something). You can test for the file's existence, but a partially-transferred file would test "true" for existing, which doesn't help.

NAME
NSTRPUSH - maximum number of STREAMS modules in a single stream
VALUES
Failsafe
Default
Allowed values
Recommended values
DESCRIPTION
This tunable defines the maximum number of STREAMS modules that can be pushed onto a stream. This provides some protection against run-
away processes that might automatically select modules to push onto a stream. It is not intended as a defense against malicious use of
STREAMS modules by system users.
Most systems do not require more than about three or four modules in a stream. However, there may be some unusual cases where more modules
are needed. The default value for this tunable allows as many as 16 modules in a stream, which should be sufficient for even the most
demanding installations and applications.
Who Is Expected to Change This Tunable?
Any customer.
Restrictions on Changing
Changes to this tunable take effect at next reboot.
When Should the Value of This Tunable Be Raised?
When the customer needs to push more STREAMS modules in a single stream.
What Are the Side Effects of Raising the Value of This Tunable?
Might allow run-away applications to unduly consume system resources.
When Should the Value of This Tunable Be Lowered?
There is no need to lower the tunable value from the default value.
What Are the Side Effects of Lowering the Value of This Tunable?
Too low of a value might cause network commands to fail.
What Other Tunable Should Be Changed at the Same Time as This One?
None.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
