Frequently Asked Questions
Q: How can I change the IRQ and I/O of ISDN board manually in Win95?
A: In Win95, you may change the IRQ of the ISDN card to another IRQ or I/O by Start>
Settings>Control Panel>System>Device Management>Multifunction>ISDN Adapter>
Property>Resource, do not select Use Automatic settings and select Change Setting.
Q: How can I solve the IRQ selftest failure in Win95 and Win31?
A: First step: In Win95, go to the Device manager to check the IRQ value of the ISDN card. You can
check this by using Start>Settings>Control Panel>System>Device Management>My
Computer>Properties.
Second step: In Win95, make sure all other cards do not conflict with your ISDN card. If you find a
conflict, remove the card or assign another IRQ to that board (this most often happens with a non-
PnP board). Reboot the computer.
General description: In Win95 and Win31, if you do not find a conflict, update your non-PnP BIOS to a
BIOS with the PnP feature. If you have a PnP BIOS and identify an IRQ conflict, change the value
manually to an unassigned IRQ. Reboot the computer after making any changes.
Q: In Windows 3.1, what does the message “System is unstable please run it later” mean?
A: This message is shown when the driver tries to allocate some memory but cannot. You’ll need to
increase your computer’s RAM size or reduce the number of programs running in Windows 3.1. You
can also try running the ISDN driver first and running the other applications later.
Q: How can I get the driver version number?
A: In Win31, you can get the version number when you install the ISDN driver. The version number
is displayed in the Welcome Window. You may also see the version number by running the AT
CONSOLE first and a terminal program later. Set the COM port of the adapter to COM3 or COM4
and enter ATI to get the version number.
In Win95, 98 or NT, run HyperTerminal with a virtual modem connected to ISDN Com1 or 2, enter the
ATI to display the version number. You may also run LOG32.EXE to view the version number
(Version 2.21 or later). In Windows 2000, you may find the driver version by placing your cursor over
the LINKSTS icon on the task bar.
Q: How can I make a connection to an ISP through Trumpets Winsock?
A: You can either modify the script file, login.cmd, to change the characteristic of your ISDN
connection, or you can login to your ISP with your username and password and select the manual
login. Enter ATZ, ATB4, and ATD#######.
Q: Does the driver support RAS in Windows 95?
A: RAS is supported in Version 2.13 and later. You can download the latest driver from http://
