Dial Using V.25bis Software

To make synchronous connections using V.25bis communications software, you must Þrst

conÞgure the I-modem using AT commands. Once the I-modem is conÞgured, run your

communications software, which takes control of the I-modem for the duration of the

connection.

ConÞguring the I-modem

Before you attempt to connect to a synchronous network, you must Þrst conÞgure the I-

modem using an asynchronous device, such as a terminal or a computer running standard

asynchronous communications software.

1. Find out which V.25bis protocol

, HDLC or character-oriented, is being used for dialing

and answering at the host computer and then set the I-modem to dial using it.

&M6 Dial using a character-oriented protocol that is similar to BISYNC.

The I-modem and the remote device must use the same 8-bit data format.

The character length must be 7 bits and either ODD or EVEN parity (ODD

is preferred), or 8 bits and NO parity.
