8 usbsksp \- Keyspan USB to serial converter driver
17 #include <sys/termio.h>
27 The \fBusbsksp\fR driver is a loadable \fBSTREAMS\fR and \fBUSBA\fR (Solaris
28 USB architecture) compliant client driver that provides basic asynchronous
29 communication support for Keyspan USB-to-serial converters. The \fBusbsksp\fR
30 driver supports the Keyspan USA19HS, USA49WG and USA49WLC models. By default,
31 the USA19HS and USA49WG models are compatible with the \fBusbsksp\fR driver and
32 no configuration or installation steps are required. (The USA49WG model is a
33 USB 2.0 device conforming to \fIUniversal Serial Bus Specification 2.0\fR and
34 the USB 2.0 host controller is required to support the USA49WG model. Note that
35 the USA49WG is not compatible with USB 1.1 host controllers). The Keyspan
36 USA49WLC model requires a firmware package that is no longer publicly available.
37 Serial device streams are built with appropriate modules that are pushed atop
38 the \fBusbsksp\fR driver by the \fBautopush\fR(8) facility.
41 The \fBusbsksp\fR module supports the \fBtermio\fR(7I) device control functions
42 specified by flags in the \fBc_cflag\fR word of the termios structure, and by
43 the IGNBRK, IGNPAR, PARMRK and INPCK flags in the \fBc_iflag\fR word of the
44 termios structure. All other \fBtermio\fR(7I) functions must be performed by
45 \fBSTREAMS\fR modules pushed atop the driver. When a device is opened, the
46 \fBldterm\fR(7M) and \fBttcompat\fR(7M) \fBSTREAMS\fR modules are
47 automatically pushed on top of the stream, providing the standard
48 \fBtermio\fR(7I) interface.
51 Use device logical names \fB/dev/term/[0-9]\fR* to access the serial ports.
52 These names are typically used to provide a logical access point for a dial-in
53 line that is used with a modem.
56 A special feature (controlled by the minor device number) is available that
57 enables a single tty line to be connected to a modem and used for incoming and
58 outgoing calls. By accessing through device logical name \fB/dev/cua/[0-9]\fR*,
59 you can open a port without the carrier detect signal being asserted, either
60 through hardware or an equivalent software mechanism. These devices are
61 commonly known as 'dial-out' lines.
64 Unlike onboard serial ports, the \fBusbsksp\fR ports cannot serve as a local
66 .SH APPLICATION PROGRAMMING INTERFACE
68 A dial-in line can be opened only if the corresponding dial-out line is closed.
69 A blocking \fB/dev/term\fR open waits until the \fB/dev/cua\fR line is closed
70 (which drops Data Terminal Ready, after which Carrier Detect usually drops as
71 well) and carrier is detected again. A non-blocking \fB/dev/term\fR open
72 returns an error if the \fB/dev/cua\fR is open.
75 If the \fB/dev/term\fR line is opened successfully (usually only when
76 carrier is recognized on the modem), the corresponding \fB/dev/cua\fR line
77 cannot be opened. This allows a modem and port to be used for dial-in (by
78 enabling the line for login in \fB/etc/inittab\fR) or dial-out (by
79 \fBtip\fR(1)) when no one is logged in on the line.
82 Device hot-removal is functionally equivalent to a modem disconnect event, as
83 defined in \fBtermio\fR(7I).
86 The \fBusbsksp\fR driver supports the standard set of \fBtermio\fR(7I) ioctl
90 Input and output line speeds can be set to the following baud rates: 0, 50,
91 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400,
92 57600, 115200, or 230400. Input and output line speeds cannot be set
93 independently. For example, when the output speed is set, the input speed is
94 automatically set to the same speed.
97 An \fBopen()\fR fails under the following conditions:
104 The unit being opened does not exist.
113 The \fB/dev/cua\fR (dial-out) device is being opened while the \fB/dev/term\fR
114 (dial-in device) is open, or the dial-in device is being opened with a no-delay
115 open while the dial-out device is open.
124 The unit has been marked as exclusive-use by another process with a TIOCEXCL
134 USB device I/O error.

209 In addition to being logged, the following messages may appear on the system
210 console. All messages are formatted in the following manner:

222 \fBDevice was disconnected while open. Data may have been lost.\fR
226 The device has been hot-removed or powered off while it was open and a possible
227 data transfer was in progress. The job may be aborted.
233 \fBDevice is not identical to the previous one on this port. Please disconnect
238 The device was hot-removed while open. A new device was hot-inserted which is
239 not identical to the original device. Please disconnect the device and
240 reconnect the original device to the same port.
246 \fBDevice has been reconnected, but data may have been lost.\fR
250 The device that was hot-removed from its USB port has been re-inserted again to
251 the same port. It is available for access but data from a previous transfer
258 \fBCannot access <\fR\fIdevice\fR\fB>. Please reconnect.\fR
262 This device has been disconnected because a device other than the original one
263 has been inserted. The driver informs you of this fact by displaying the name
264 of the original device.
270 \fBNo valid firmware available for Keyspan usa49wlc usb-to-serial adapter.
