*
* postio now can be run as separate read and write processes, but requires that
* you write a procedure called resetline() and perhaps modify readline() some.
* I've already tested the code on System V and it seems to work. Ninth Edition
* and BSD code may be missing.
*
* By request I've changed the way some of the setupline() procedures (eg. in the
* System V implementation) handle things when no line has been given. If line is
* NULL the new setupline() procedures try to continue, assuming whoever called
* postio connected stdout to the printer. Things will only work if we can read
* and write stdout!

* In the original code readline() returned FALSE when read() returned 0 and we
* get into a loop that never ends - because the write process is hung. In the
* one process implementation having read return 0 is legitimate because the line
* is opened for no delay, but with two processes the read() blocks and a return
* value of 0 should never occur. From my point of view the real problem is that
* the write() call hangs on 3B2 DKHOST systems and apparently doesn't anywhere
* else. If the write returned anything less than or equal to 0 writeblock() would
* shut things down. The kludge I've implemented counts the number of consecutive
* times read() returns a 0 and if it exceeds a limit (100) the read process will
* shut things down. In fact one return of 0 from read() when we're in the two
* process mode is undoubtedly sufficient and no counting should be necessary!!!
* Moving the check to getstatus() should also work and is probably where things
