Does anybody out there know how to program the serial port from Amiga Basic so it runs at the correct MIDI rate (31.25 Kbaud)? I friend of mine is writing compositional programs from basic and has the required hardware for RS-232 <-> midi conversion, but has found that he can only set the serial port to the cannonical baud rates 1200,2400,4800, etc. Hints, anyone?

Alternatively, you can set SER: to 31.2K from Preferences, although performing I/O to SER: won't give you the asynchronous performance you want. Why, Why didn't you post this to an Amiga newsgroup?? +----------------------------------------------------------------------------+ | Dallas J.

You can't do it from Basic, the performance requirements are way outside of what it can do. Also you need to set some serial device parameters of which only a small subset can be manipulated from Basic. -- ,u, Bruce Becker Toronto, Ontario a /i/ Internet: bdb@becker.UUCP, bruce@gpu.utcs.toronto.edu `\o\-e UUCP: ...!uunet!mnetor!becker!bdb _< /_ "Making the world safe for demography" - Western Culture (tm) Yoghurt

It was on a Fish disk awhile back. I wonder if using a Basic compiler would be able to make enough improvement in the speed to to any good. -- /%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%\ | | You gotta have smelled a lot of | | dgold@basso.actrix.gen.nz | mule manure before you can sing | | | like a hillbilly.
