NAME

       pcser - PCMCIA serial card device driver

SYNOPSIS

       serial@<socket>:pcser

       serial@<socket>:pcser,cu

       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 identification
		   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 command 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  com-
       munications  port.  For example, the /etc/uucp/Devices file needs to be updated to use UUCP. See Overview of UUCP in the System Administra-
       tion Guide. For PPP on the serial port, see pppd(1M) and Solaris PPP Overview in the System Administration Guide.

   Special Files
       The serial devices in /dev/term and /dev/cua are named by socket number. 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.

       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.
