Aloha

About 2 years ago I was debugging a problem that we suspected was in 
drvAscii. I decided to debug this problem on UNIX so I could use the
UNIX compliation tools and debuggers. To this end I created 'glue'
code so as to be able to run drvSerial and drvAscii on UNIX (the intent
was to leave those drivers untouched, as much as possible). This all
worked fine.

The 'glue' code is mainly system call translations (semaphores, 
spawns, ...). This code should be subsumed into the drivers. 

Since that time I have successfully driven an instrument rotator, whose
motor controller has a serial interface,  using the 'glued' drvSerial and
drvAscii, along with an updated tnet driver.

In most cases, the EPICS databases using drvAscii and developed for Vxworks, 
will run on the r3.14 UNIX platform by simply changing the port designations 
(which should be a macro substitution), with the 'glue' drivers.

I will try and update the drivers to eliminate the 'glue' sometime soon.

cheers,
