NAME
usbsprl - Prolific PL2303 USB to serial converter driver
SYNOPSIS
#include <fcntl.h>
#include <sys/termio.h>
usbsprl@unit
DESCRIPTION
The usbsprl driver is a loadable STREAMS and USBA (Solaris USB archi‐
tecture) compliant client driver that provides basic asynchronous com‐
munication support for Prolific PL2303 USB-to-serial converters. Sup‐
ported devices include PL2303H, PL2303HX and PL2303X. Serial device
streams are built with appropriate modules that are pushed atop the us‐
bsprl driver by the autopush(8) facility.
The usbsprl module supports the termio(4I) device control functions
specified by flags in the c_cflag word of the termios structure, and by
the IGNBRK, IGNPAR, PARMRK and INPCK flags in the c_iflag word of the
termios structure. All other termio(4I) functions must be performed by
STREAMS modules pushed atop the driver. When a device is opened, the
ldterm(4M) and ttcompat(4M) STREAMS modules are automatically pushed
on top of the stream, providing the standard termio(4I) interface.
Use device logical names /dev/term/[0-9]* to access the serial ports.
These names are typically used to provide a logical access point for a
dial-in line that is used with a modem.
A special feature (controlled by the minor device number) is available
that enables a single tty line to be connected to a modem and used for
incoming and outgoing calls. By accessing through device logical name
/dev/cua/[0-9]*, you can open a port without the carrier detect signal
being asserted, either through hardware or an equivalent software mech‐
anism. These devices are commonly known as 'dial-out' lines.
APPLICATION PROGRAMMING INTERFACE
A dial-in line can be opened only if the corresponding dial-out line is
closed. A blocking /dev/term open waits until the /dev/cua line is
closed (which drops Data Terminal Ready, after which Carrier Detect
usually drops as well) and carrier is detected again. A non-blocking
/dev/term open returns an error if the /dev/cua is open.
If the /dev/term line is opened successfully (usually only when carrier
is recognized on the modem), the corresponding /dev/cua line cannot be
opened. This allows a modem and port to be used for dial-in (by en‐
abling the line for login in /etc/inittab) or dial-out (by tip(1)) when
no one is logged in on the line.
Device hot-removal is functionally equivalent to a modem disconnect
event, as defined in termio(4I).
IOCTLS
The usbsprl driver supports the standard set of termio(4I) ioctl calls.
Input and output line speeds can be set to the following baud rates:
75, 150, 300, 600, 1200, 1800, 2400, 4800, 9600, 19200, 38400, 57600,
115200, 230400 or 460800. Input and output line speeds cannot be set
independently. For example, when the output speed is set, the input
speed is automatically set to the same speed.
ERRORS
An open() fails under the following conditions:
ENXIO The unit being opened does not exist.
EBUSY The /dev/cua (dial-out) device is being opened while the
/dev/term (dial-in device) is open, or the dial-in device is
being opened with a no-delay open while the dial-out device is
open.
EBUSY The unit has been marked as exclusive-use by another process
with a TIOCEXCL ioctl() call.
EIO USB device I/O error.

DIAGNOSTICS
In addition to being logged, the following messages may appear on the
system console. All messages are formatted in the following manner:
Warning: <device path> (usbsprl<instance num>): Error Message...
Device was disconnected while open. Data may have been lost.
The device has been hot-removed or powered off while it was open
and a possible data transfer was in progress. The job may be
aborted.
Device is not identical to the previous one on this port. Please dis‐
connect and reconnect.
The device was hot-removed while open. A new device was hot-in‐
serted which is not identical to the original device. Please dis‐
connect the device and reconnect the original device to the same
port.
Device has been reconnected, but data may have been lost.
The device that was hot-removed from its USB port has been re-in‐
serted again to the same port. It is available for access but data
from a previous transfer may be lost.
Cannot access <device>. Please reconnect.
This device has been disconnected because a device other than the
original one has been inserted. The driver informs you of this fact
by displaying the name of the original device.
The following messages may be logged into the system log. They are for‐
matted in the following manner:
<device path><usbsprl<instance number>): message...
Input overrun.
Data was lost.
