Subject: USB Serial Support for AMFORTH 4.6 on Arduino Micro
All:
I have developed a package for AMFORTH 4.6 that causes the USB engine on the
ARDUINO Micro to enumerate as a USB ACM Communication Device (CDC 1.2 PSTN).
The goal is to provide a USB serial port that requires no special driver
support on any operating system. (That has not yet been achieved with Windows.)
It is however, known to enumerate and work properly on UBUNTU 10.10,
out-of-the-box. That is without any special driver support. Throughput is about
390K simplex and 150Kbps full-duplex. It supports the SetLineCoding,
GetLineCoding request. Dataset signals DTR and RTS are controllable via the
SetControlLineState command.

Presently, it's pretty large. Last time I looked, free space after loading is
1800+ cells. It requires multi-task support. AMFORTH 4.6 itself is unmodified.
I would be interested in contributing it to the cause. How do I go about doing
that?

Jeffrey Rosenwald
