Yes, difficult to enquire about but fairly easy to figure out. Soon we should have a driver to support atleast Entrega USB -> Serial widgets. As Nick said I can do printfs in the firmware out the serial port and had a protype perl driver for it working. Now I'm working on splitting functionality between the firmware and an sio type driver. It's going somewhat slow due to my lack of time, knowledge and bug fixing of various things such as the sdcc 8051 compiler. In a couple of weeks I hope to have my first cut working. My goal is to be able to run tip to talk out the serial port and then test it at 230K. I've heard that the Belkin device is very similar. BTW if someone commited the sdcc port more people could play with it and write their own firmware. BTW2 I found a bug in more port in which it didn't install the headers for sdcc. I guess I should pr my pr. Doug A. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
