My great thanks to Jim Murray for this driver. I have it working on SV/AT with a standard AT comm port configuration. It wasn't clear from the posting that this driver might make sense even for those of us without exotic async hardware. One of the biggest curses of SV/AT has been hangs in the async driver. Preliminary tests suggest that this driver does not have those problems. In order to use it with SV/AT, you'll need to fix the declarations of open_device and close_device in asy.c. They are first declared in forward declarations as "static void". When the actual declaration is given, the "static" is omitted. This causes the compiler to complain. You want to change void open_device(aip, opening_getty_version) to static void open_device(aip, opening_getty_version) and similarly for close_device. Other than that the installation went smoothly with my 2.4 system. I'm using it at 2400 baud. The README suggests that performance may not be as good as the Microport driver if you have the standard async chip. But of course I wouldn't notice that at 2400. I'm more interested in reliability than speed.
