VIOTBL.DCP statement. If it is not, arrange the order of the statements so
that this requirement is satisfied.) If there is no COM.SYS or VCOM.SYS
statement, add these to your config.sys file (see the example for the proper
syntax). Be sure these statements are between the KEYBOARD.DCP and
VIOTBL.DCP entries.
Modify the COM.SYS statement using the values you recorded in Step 4:
DEVICE=C:\OS2\BOOT\COM.SYS ( x , yyyy , n )
DEVICE=C:\OS2\MDOS\VCOM.SYS
Where: x is either 1, 2, 3, or 4 (COM4 is recommended)
yyyy is the I/O Port Address ( in Hexadecimal) of the modem
n is the IRQ number of the modem
Example: DEVICE=C:\OS2\BOOT\COM.SYS (4,F400,11)
DEVICE=C:\OS2\MDOS\VCOM.SYS
10. Save the new config.sys file. Check that the installation diskette has been
removed from the floppy disk drive and then reboot the system.
11. You will now be able to use your communications programs at the COM Port
you assigned in Step 9.
12. After you have setup your applications to use the modem, you will need to
issue an AT Command to configure the modem to use the PSTN ( P ublic
S witched T elephone N etwork) of your country. The modem can be config-
ured for: Canada, Japan, and the United States.
13. To configure the modem’s country setting, open a terminal program. At the
command prompt, type: at<enter> . The response should be “OK”. Now type
one of the following commands depending on the country where the modem
will be operated.
Canada: at%T19,0,1c<enter>
Japan: at%T19,0,10<enter>
United States: at%T19,0,19<enter>
If the command was properly entered, the response will be “ OK ”. A response
of “ ERROR ” will indicate an incorrect entry. After the command has been
entered and accepted, the modem will default to this setting every time you
turn on the system. To find your current country setting, issue the command
ATI9<enter> . The response will indicate your current country setting (Canada,
Japan, or North America).
