- RE - MacApp & Serial Communication
-
- Hi Margaret & Charles,
-
- TAsyncHandler and TAsyncDocument MacApp object already exists and handles
- serial communication.
- See (and order to MADA Europe) MacAnswer application (author: Carl Nelson &
- Associates).
- Reference: MacApp Goodies Volume 1 (GV-1)

- UAsync
-
- Carl Nelson
- 4007 Nassau Place
- Everett, WA
-
- March 1987
-
- See the March Issue of MacApp Developer's Association for notes and
- commentary on the UAsync Unit.
-
- The UNIT is intended to show how to use the Async port from
- a MacApp program. It uses the same approach that the AppleTalk
- unit in MacApp 1.0B1 used.
-
- The methods to look at for overriding are:
-
- TAsyncHandler.DoIdle which checks for incoming characters.
- You may want to handle the characters as they
- arrive instead of posting an event.
-
- TAsyncHandler.ObeyAppEvt should you wish to post events then you must
- override this method.
-
-
- You will call IAsyncHandler during IMyApplication and return success
- or fail to gMyApplication.RUN should we fail to setup the port properly.
-
- The example program MacAnswer shows use of the unit to build a dumb TTY.
-

-
- About those Building Blocks:
- Feel free to send MADA.Europe and MADA your enhancements of those old 1.0B1
- blocks, (you know it "don't reinvent the weel").

- Regards,
- Eric
