Get on to APDA. There's a disk called "HyperCard Serial Communications
Toolkit V2.5"

It's good, but naturally very slow to drive from HyperCard scripts.
It's just what you want:

		EXCEPT.....

There's no CLOSE on the serial port that you can call to drop the modem
signals. I used another XCMD (SendSerial by Ken D. at Apple) to close
the port. If I leave DTR up in my application the box I'm controlling
won't go away and do what it's meant to. I got SendSerial off the
"HyperCard Developers Package v1.0b1".
