SYNOPSIS
serial@<socket>:pcser
serial@<socket>:pcser,cu
DESCRIPTION
The pcser PCMCIA serial card device driver supports asynchronous serial
I/O access to any PCMCIA card that that complies with Revision 2.1 of
the PCMCIA standard and which represents an 8250-type UART interface.
PRECONFIGURE
If a PC card modem or serial device is recognized, the pcser device
driver is automatically loaded, ports and IRQs allocated, and special
files created (if they don't already exist).
CONFIGURATION
Configuration steps include initial installation and configuration,
identifying an unrecognized device and misidentifying a recognized
device.
Initial Installation and Configuration
1. Install the Solaris software.
2. Boot the system.
3. Insert the modem or serial device.
Identifying an Unrecognized Device
If you insert a PC card modem or serial device and it is not recognized
(that is, no special files are created under /dev/cua or /dev/term),
use the prtconf command to find the problem:
1. Become root.
2. Run the prtconf -D command to see if your modem or serial device is
recognized. An unrecognized device will appear at the end of the
prtconf output. For example:
# prtconf -D
. . .
pcic, instance #0 (driver name: pcic)
. . .
pccard111.222 (driver not attached)
3. If your device is not recognized, use the add_drv command to add
the name of your device as another known alias for pcser devices.
For example, type the following at the command line:
# add_drv -i'"pccard111.222"' pcser
Note -
Include the double quotes in single quotes to keep the
shell from stripping out the double quotes. Use the identi‐
fication string listed in the prtconf output. Use the
entire string in the add_drv command. See add_drv(1M).
Misidentifying a Recognized Device
1. Run the prtconf -D command to see if your modem or serial device is
erroneously recognized as a memory card. If the device is incor‐
rectly recognized as a memory card, the output of the prtconf com‐
mand could show:
# prtconf -D
. . .
pcic, instance #0 (driver name: pcic)
. . .
memory, instance #0 (driver name: pcmem)
pcram, instance #0 (driver name: pcram)
2. Use the Configuration Assistant to identify the memory resource
conflict, and add correct information for the device on the
View/Edit Devices menu. Typically, the problem may be a resource
conflict between device memory settings. A PC Card adapter chip
that is not fully supported may also be the cause of the problem.
3. To work properly with the Solaris operating environment, all
devices must be accounted for, even those the Solaris environment
does not support. The Configuration Assistant software accounts for
all devices in your system.
Additional Configuration
When adding a new serial port or modem to the system, you often need to
edit configuration files so that applications can use the new communi‐
cations port. For example, the /etc/uucp/Devices file needs to be
updated to use UUCP. See Overview of UUCP in the System Administration
Guide. For PPP on the serial port, see pppd(1M) and Solaris PPP Over‐
view in the System Administration Guide.
Special Files
The serial devices in /dev/term and /dev/cua are named by socket num‐
ber. A card inserted in socket 0 is pc0, and socket 1 is pc1.
Hot Plugging
If a PC Card modem or serial device is unplugged while in use, the
device driver returns errors until the card is replaced in the socket.
The device must be closed and reopened with the card reinserted before
the device begins working again. The restart process depends on the
application. For example, a tip session automatically exits when a
card in use is unplugged. To restart the system, you must restart the
tip session.
FILES
/kernel/drv/pcser pcser driver
/dev/term/pcn dial-in devices
/dev/cua/pcn dial-out devices where: n is the
PCMCIA physical socket number.

pcser: socket n soft silo overflow
The driver's character input ring buffer overflowed before it could
be serviced.
pcser: socket n unable to get CIS information
The CIS on the card has incorrect information or is in an incorrect
format. This message usually indicates a non-compliant card.
