UVISOR(4) Device Drivers Manual UVISOR(4)


uvisorUSB support for the PalmOS based PDAs


To compile this driver into the kernel, place the following lines in your kernel configuration file:
device uvisor
device ucom
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):


The uvisor driver provides support for USB based PalmOS PDAs, like Handspring Visor, Palm Mxxx series, and Sony Clie.
The device is accessed through the ucom(4) driver which makes it behave like a tty(4). The device has several ports for different purposes, each of them gets its own ucom(4) device. The attach message describes the purpose of each port.
The usual Pilot tools can be used to access the attached device on the HotSync port.

  • Aceeca Mez1000 RDA

The uvisor driver was adopted from NetBSD 1.5 in August 2002. This manual page was adopted from NetBSD by Tom Rhodes ⟨⟩ at that time.


The code to provide multiple ucom(4) instances has not yet been ported from NetBSD. It is unclear whether this driver works in its current state.
