NAME

     pcser - PCMCIA serial card device driver

SYNOPSIS

     serial@<socket>:pcser

     serial@<socket>:pcser,cu

DESCRIPTION

     The pcser PCMCIA serial card device  driver  supports  asyn-
     chronous serial I/O access to any PCMCIA card that that com-
     plies with Revision 2.1 of the  PCMCIA  standard  and  which
     represents an 8250-type UART interface.

PRECONFIGURATION

     If a PC card modem or serial device is recognized, the pcser
     device  driver is automatically loaded, ports and IRQs allo-
     cated, and special files  created  (if  they  don't  already
     exist).

CONFIGURATION

     Configuration steps include initial installation and  confi-
     guration,  identifying an unrecognized device and misidenti-
     fying 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 incorrectly 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  sup-
        ported 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 sys-
        tem.

  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  communications  port.  For  example,  the
     /etc/uucp/devices  file  needs to be updated to use UUCP and
     PPP. See "Overview of UUCP" in System Administration  Guide,
     Volume 3.

  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  rein-
     serted  before  the device begins working again. The restart
     process depends on the application. For example, a tip  ses-
     sion 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.

DIAGNOSTICS

     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.
