configuring integrated modem?

» close window

The Question is:

 
Is is possible to install an internal modem
in a AS1000A i.e USR 14400 and how would it be
done ?
 


The Answer is :

 
  The directions included with the PBXDF-AA modem or similar should include
  this information.
 
  The hardware portion of the installation on the typical Alphaserver series
  system consists of using the ECU to select the generic ISA driver file
  included on the ECU distribution kit.  The PBXDF-AA is a 14.4 zoom/fax
  modem that uses 8 I/O addresses and an IRQ.  You will have to tell the
  ISA driver about the requirements for your specific modem device.  One
  local system has used the modem configured at 2F8 and IRQ 3 -- this will
  cause the ECU to disable the on-board COM2 port (after a warning).  The
  modem is then set up for COM2 and placed in the configured slot.
 
  When OpenVMS is booted, use SET HOST/DTE to TTA0: (or the terminal that
  is associated with the COM port you used), and use the modem command set
  (AT or otherwise) to disable response codes, disable the forcing of DSR
  (pin 6), honor DTR (pin 20) to reset or to enter command mode, and honor
  DCD (pin 8).  You will want to set this up so that if the modem is reset,
  it reloads its "brains" correctly.
 
  With an AT-style command set, this sequence of commands looks like:
 
    AT Q1 &S1 &D2 (or &D3) &C1 &W0 &Y0
 
  You'll need to decide on the auto-answer behaviour and various other
  modem-specific settings, as well.
 
  If you have problems with the SET HOST/DTE, connect a terminal or PC
  with a terminal emulator directly to the modem to configure it.  (This
  avoids problems establishing the connection to the modem port that can
  result from an incorrectly configured modem.)
 
  Now please see the other discussions on how to configure a modem on an
  OpenVMS system that have been posted in the Ask-The-Wizards area in the
  past -- these discussions will cover the host portion of the necessary
  OpenVMS modem configuration process.
