NAME
     pcser - PCMCIA serial card device driver

SYNOPSIS
     serial@:pcser


     serial@: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.

PRECONFIGURE
     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 informa-
              tion 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  sup-
              port. 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  communications  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 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  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

DIAGNOSTICS
     pcser: socketn soft silo overflow

         The driver's  character  input  ring  buffer  overflowed
         before it could be serviced.


     pcser: socketn 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.
