Is "line -t n" common?

[Hershel Belkin]

A simple question perhaps, but can anyone tell me if the "-t"
option is "standard" on the "line" command, or is it an extension
added by HP on HP-UX?  It provides for a "time-out" termination of
the command if nothing is received...ie.  line -t 5  will wait 
about 5 seconds for a response, then exit with returned status of "1"
indicating that no input was read.

Although this option works on HP-UX, it is undocumented even in their
manuals!  I'd like to use it, but might opt not to if this is
non-standard (or at least not common :-)

Thanks for any insights!
