INSTRUCTIONS FOR INSTALLING PCXDF-AA DATA/FAX MODEM IN MIKASA UNDER OPENVMS.
Configure the modem jumpers to COM7 as shown in the modem manual. This
corresponds to COM3 with the IRQ set to 5 rather than the default of 4.
Install the modem in an empty EISA slot in the Mikasa. Make a note of which
slot it is located in. The EISA slots are numbered 1 through 8 with slot 1
being at the top.
Power up the system. Place the ECU diskette in the floppy drive. Type RUNECU at
the console prompt. Following the ECU procedure, select step 2 and add the
modem card to the appropriate slot using AISA1010.CFG. On some versions, this
file may be labled OSF ISA COM/MODEM/LPT but it will work with VMS also. Next
go to step 3 and set the first serial port to COMx. Set the IRQ to 5 and the
address to 3E8h. Make sure that the second serial port and the parallel port
are not enabled. Save the configuration, power cycle the system and then boot
OpenVMS.
Log into the system account. Type SHOW DEV T to display available serial lines.
In most cases you will just see TTA0: In this case, the modem will be assigned
to the next available device which would be TTB0: as shown below. If TTB0: is
already assigned then use TTC0: etc.
Next you will need to run SYSMAN as follows:
$ MCR SYSMAN
IO SHOW BUS - Make note of the CSR address for the floppy device.
IO CONN TTB0:/DRIVER=SYS$YSDRIVER.EXE/NODE=%X00050003/VECTOR=20 -
/ADAPT=3/CSR=%XFFFFFFFF85672000
EXIT
$
NOTE: /node=%x The 5 is the IRQ selected for the board and the 3
is the slot on the EISA bus. Use the appropriate
slot number corresponding to the module location
in your system.
/vector= Calculate the vector using IRQ * 4. Since we are
using IRQ5, this number is 20.
/adapt= This is the TR number for the EISA bus obtained from the
show bus display. This number may not be displayed if you
do not have any EISA devices installed. In this case, use 3.
/driver= YSDRIVER
/csr=%x This must be identical to the floppy address obtained above.
In order to access the modem, type the following command lines:
$ SET TERM/PERM/ALT/MODEM TTB0:
$ SET HOST/DTE TTB0:
At this point you can access the modem using the AT command set.
Note that the CSR used in the sysman command sequence may change when any of a
number of system changes take place such as an OS or firmware update, memory
configuration changes or layered product installation. You should check that
the correct CSR is being used any time system changes are made.
