I've got a USB -> RS232 adapter I'm trying to get working on 5.3-RELEASE. I've seen a lot of comments about these kind of things that seem to indicate that they can be used (I occasionally have needs to use this lappy as a serial console, and I'd like to use it to demonstrate a serial barcode scanner that we have - normally, tip would work great for this, but the laptop doesn't have a native RS-232 port). Anyway, I get the impression that I'm missing some early, basic steps to get this working. dmesg shows: ugen0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 2 But neither tip nor cu seems to talk to ugen0 very well. Other posts I've seen seem to indicate that I need to be talking to a ucom0 device, but I see nothing like that in /dev. Is there something missing from my kernel? I haven't been able to find any reference to ucom in the GENERIC or NOTES files. Any advice/pointers is welcome. TIA. --=20 Bill Moran Potential Technologies http://www.potentialtech.com Be advised -- usb->serial adapters in general can have problems with real world devices that need serial port control lines as the usb dongles do not support them at all. As 'replacements' for a real serial port, they are a dismal failure, unless you are talking to a device that _only_ uses TxD, Rxd and Gnd. I have had to try these toys on newer laptops (sans serial ports!) to communicate with PLC's etc and they do not work.=20 This is not an O/S dependancy, the dongle and the USB protocol do not=20 support the hardware handshake lines. mjt --=20 A: Because it fouls the order in which people normally read text.
