Digi AccelePort Driver
- This driver supports the Digi AccelePort USB 4 device, a 4 port
- USB serial converter. The driver does NOT yet support the Digi
- AccelePort USB 2 or 8.
-
- The driver supports open, close, read, write, termios settings (baud
- rate, word size, parity, stop bits, hardware/software flow control,
- CREAD), DTR/RTS, and TIOCMGET/SET/BIS/BIC ioctls. It has not been
- thoroughly tested, but it seems to be working reasonable well. There
- is more work to do, including flow control, ioctls, and support for
- the Digi AccelePort USB 2 and 8.
+ This driver supports the Digi AccelePort USB 2 and 4 devices, 2 port
+ (plus a parallel port) and 4 port USB serial converters. The driver
+ does NOT yet support the Digi AccelePort USB 8.
+
+ The driver is generally working, though we still have a few more ioctls
+ to implement and final testing and debugging to do. The paralled port
+ on the USB 2 is supported as a serial to parallel converter; in other
+ words, it appears as another USB serial port on Linux, even though
+ physically it is really a parallel port. The Digi Acceleport USB 8
+ is not yet supported.
