3.\" 4.Dd August 12, 2004 5.Dt VKBD 4 6.Os 7.Sh NAME 8.Nm vkbd 9.Nd the virtual AT keyboard interface 10.Sh SYNOPSIS --- 114 unchanged lines hidden (view full) --- 125.Pp 126On the last close of the control device, the virtual AT keyboard is removed. 127All queued scan codes are thrown away. 128.Sh SEE ALSO 129.Xr kbdcontrol 1 , 130.Xr atkbdc 4 , 131.Xr psm 4 , 132.Xr syscons 4 |
133.Sh HISTORY 134The 135.Nm 136module was implemented in 137.Fx 6.0 . 138.Sh AUTHORS 139.An Maksim Yevmenkin Aq m_evmenkin@yahoo.com |
140.Sh CAVEATS 141The 142.Nm 143interface is a software loopback mechanism, and, thus 144.Xr ddb 4 145will not work with it. 146Current implementation of the 147.Xr syscons 4 148driver can accept input from only one keyboard, even if it is virtual. 149Thus it is not possible to have both wired and virtual keyboard to be active 150at the same time. 151It is, however, in principal possible to obtain AT scan 152codes from the different sources and write them into the same virtual keyboard. 153The virtual keyboard state synchronization is the user's responsibility. |
