- 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 architecture) compliant client driver that provides basic asynchronous communication support for Prolific PL2303 USB-to-serial converters. Supported devices include PL2303H, PL2303HX and PL2303X. Serial device streams are built with appropriate modules that are pushed atop the usbsprl driver by the autopush(1M) facility.

The usbsprl module supports the termio(7I) 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(7I) functions must be performed by STREAMS modules pushed atop the driver. When a device is opened, the ldterm(7M) and ttcompat(7M) STREAMS modules are automatically pushed on top of the stream, providing the standard termio(7I) 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 mechanism. These devices are commonly known as 'dial-out' lines.

Unlike onboard serial ports, the usbsprl ports cannot serve as a local serial console.

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 enabling the line for login in /etc/inittab) or dial-out (by tip(1), or uucp(1C)) when no one is logged in on the line.

Device hot-removal is functionally equivalent to a modem disconnect event, as defined in termio(7I).

ioctls

The usbsprl driver supports the standard set of termio(7I) 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 disconnect and reconnect.

The device was hot-removed while open. A new device was hot-inserted which is not identical to the original device. Please disconnect 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-inserted again to the same port. It is available for access but data from a previou 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 formatted in the following manner:

<device path><usbsprl<instance number>): message...
Input overrun

Data was lost.
