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). If you use the
36 Keyspan USA49WLC model, you must download and install a firmware package to
37 enable the device to work with the \fBusbsksp\fR driver. See the Keyspan
38 website (\fIhttp://www.keyspan.com/downloads/sun/\fR) for more information.
39 Serial device streams are built with appropriate modules that are pushed atop
40 the \fBusbsksp\fR driver by the \fBautopush\fR(1M) facility.
43 The \fBusbsksp\fR module supports the \fBtermio\fR(7I) device control functions
44 specified by flags in the \fBc_cflag\fR word of the termios structure, and by
45 the IGNBRK, IGNPAR, PARMRK and INPCK flags in the \fBc_iflag\fR word of the
46 termios structure. All other \fBtermio\fR(7I) functions must be performed by
47 \fBSTREAMS\fR modules pushed atop the driver. When a device is opened, the
48 \fBldterm\fR(7M) and \fBttcompat\fR(7M) \fBSTREAMS\fR modules are
49 automatically pushed on top of the stream, providing the standard
50 \fBtermio\fR(7I) interface.
53 Use device logical names \fB/dev/term/[0-9]\fR* to access the serial ports.
54 These names are typically used to provide a logical access point for a dial-in
55 line that is used with a modem.
58 A special feature (controlled by the minor device number) is available that
59 enables a single tty line to be connected to a modem and used for incoming and
60 outgoing calls. By accessing through device logical name \fB/dev/cua/[0-9]\fR*,
61 you can open a port without the carrier detect signal being asserted, either
62 through hardware or an equivalent software mechanism. These devices are
63 commonly known as 'dial-out' lines.
66 Unlike onboard serial ports, the \fBusbsksp\fR ports cannot serve as a local
68 .SH APPLICATION PROGRAMMING INTERFACE
70 A dial-in line can be opened only if the corresponding dial-out line is closed.
71 A blocking \fB/dev/term\fR open waits until the \fB/dev/cua\fR line is closed
72 (which drops Data Terminal Ready, after which Carrier Detect usually drops as
73 well) and carrier is detected again. A non-blocking \fB/dev/term\fR open
74 returns an error if the \fB/dev/cua\fR is open.
77 If the \fB/dev/term\fR line is opened successfully (usually only when
78 carrier is recognized on the modem), the corresponding \fB/dev/cua\fR line
79 cannot be opened. This allows a modem and port to be used for dial-in (by
80 enabling the line for login in \fB/etc/inittab\fR) or dial-out (by
81 \fBtip\fR(1), or \fBuucp\fR(1C)) when no one is logged in on the line.
84 Device hot-removal is functionally equivalent to a modem disconnect event, as
85 defined in \fBtermio\fR(7I).
88 The \fBusbsksp\fR driver supports the standard set of \fBtermio\fR(7I) ioctl
92 Input and output line speeds can be set to the following baud rates: 0, 50,
93 75, 110, 134, 150, 200, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400,
94 57600, 115200, or 230400. Input and output line speeds cannot be set
95 independently. For example, when the output speed is set, the input speed is
96 automatically set to the same speed.
99 An \fBopen()\fR fails under the following conditions:
106 The unit being opened does not exist.
115 The \fB/dev/cua\fR (dial-out) device is being opened while the \fB/dev/term\fR
116 (dial-in device) is open, or the dial-in device is being opened with a no-delay
117 open while the dial-out device is open.
126 The unit has been marked as exclusive-use by another process with a TIOCEXCL
136 USB device I/O error.
