Figure 2-16. Linking Virtual Modem to Com Port
The ISDN modems are used for the following purposes:
The Async to Sync PPP modem is used for 64K Internet Access.
X.75 Transparent modem is used for BBS access and file transfer.
The Universal-1 and -2 are multi-purpose modems. In Universal modem mode,
the ISDN driver selects HDLC as the default, but you can change to the appropri-
ate protocol through the ATBn commands (see Chapter 3). Before making a con-
nection, you can change through Start»Settings»Control Panel»Modems»ISDN
modem»Properties»Connection, Advanced»Extra settings.
You can use the Universal modems for 128K MLP Internet access, in which case
both ISDN ports must have the Universal modem selected.

the default modem setting pertaining to each of the two ISDN COM ports/
modems. Select Start»Settings»Control Panel»Modems»ISDN modem for
ISDN ComPorts»Properties»Connection (as shown in Figure 2-17). Set Data
bits to 8, Parity to None, and Stop bits to 1. Do not select to use FIFO buffers
