Nope. uscom is afaik only tested so far with HP graphing calculators. It is *really* simple, just provides a way to transfer data, it does not allow setting port speed etc. Also it is not built into GENERIC at present so it requires a custom kernel. ucom(4) is a different layer. ucom attaches *to* the hardware device driver (uftdi, uark, ubsa, uscom, ...) to provide tty(4)-like access. > * If I buy a random USB-to-serial dongle, is it likely that it'll work > with either uscom(4) or ucom(4)? If not, does anyone have any hardware > recommendations, i.e. what do you use? My suggestion: pick a random cheap single-port rs232/usb adapter, don't spend much money on it. If it doesn't work, try a different one, and send lsusb -v outpout and see if anyone would like to have the non-working device to play with and try and add support.. (multi-port ones may also work, but you have a higher chance of a single-port one "just working"). FTDI clones might be particularly cheap at the moment :)
