emulation also available through CAPI. Other API modes, such as NDIS
and VCOMM, will be supported by a later release.
1. Run Windows NT.
2. Plug the PC Card into your laptops PCMCIA slot.
3. Insert the Windows NT driver disk and click Start, Settings, Control
Panel, and then double-click PC Card (PCMCIA). Note the resources

Chapter 3—Application Program Interfaces (APIs)

20 MultiMobile
Chapter 3—Application Program Interfaces (APIs)
Introduction
The MultiMobile supports three application program interfaces (APIs)
VCOMM, CAPI, and NDISto connect to popular ISDN communication
software packages. An API is the interface between application programs
and hardware (PC Card) that permits the application programs to talk to
and drive the ISDN PC Card. Select the appropriateAPI for your software
package and application.
VCOMMuses virtual COM ports. The MultiMobile works exactly like
an ISDN external terminal adapter, operating with typical terminal
emulation packages such as Windows 95 Hyper Terminal, MultiExpress for
Windows, Telix, pcAnywhere, etc. In VCOMM mode, ISDNAT commands
are usually used to configure the PC Card.
CAPIdesigned for CAPI compliant applications (which are widely used
in Europe) such as Dial-Up-Networking. The RVS-COM application suite
uses CAPI.
NDISallows you to use Dial-Up Networking to create remote note
connections or Internet connections. In NDIS, you have to specify SPIDs
and switch types.
This chapter provides information on how to use APIs to configure your
MultiMobile and describes the features of each API.
Note: Included with the PC Card is the MultiMobile Global Wizard
diskette. Use the Global Wizard to change the country code, which
enables you to comply with the local telecom authority, thereby
optimizing modem performance. The MultiMobile Global Wizard is for
use with VCOMM mode only.
