MultiMobile 21
Chapter 3—Application Program Interfaces (APIs)
VCOMM (Virtual Communications Port)
With VCOMM, 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, ISDN AT commands usually are used
to configure the PC Card.
Note: Fax/Modem over ISDN and ISDN Phone over ISDN functions are
available under VCOMM API.
Making Modem over ISDN Data Calls
The Fax/Modem over ISDN function permits you to talk seamlessly
through ISDN line to analog fax/modem devices at remote locations. This
function is available only under VCOMM API. Make sure the current API
setting is correct.
To make a Modem over ISDN data call:
1. In the Configuration Utility, open the COM Port Setting tab and
select Modem over B-channel. Then click OK.
2. Enter ATDM and the phone number (for example: ATDM5553000)
under terminal mode (such as Hypertrm in Windows 95) to make
Modem over ISDN data calls.
3. To answer incoming modem calls through ISDN line, in the
Configuration Utility, open the General tab and select Answered by
Modem. Then click OK.
