Synchronous Dialing from an IBM AS 400

The modem operates as a synchronous originate modem with the IBM AS 400. Set

the modem to Option Set 3—no reconfiguration from this Option Set is

necessary. The AS 400 supports switched operation with call origination via a V.25bis compliant call establishment driver.Using Option Set 3 allows it to be driven by APPC/APPN, the bit-synchronous protocol supported by the IBM AS 400.

In an AS 400-to-AS 400 (mainframe-to-mainframe) environment, the setting of the Calling Number parameter is critical to ensure the AS 400 operates properly with the modem. Rather than entering the phone numbers you will be calling, set CALLNBR to *NONE. This setting allows you to properly utilize V.25bis commands.

Chapter 3, Automatic Calling Interfaces, in the 326X Series Modem Reference Guide, describes bit-synchronous protocol frame formats.

Option Set 4—Async Answering Central Site without ACU (Models 3260/62/65/67)

Changing Default Configuration Settings

Depending on application requirements, you may need to change the following:

•The Buffer Delay feature (AT*DB, EC/DC OPTS category), when enabled, allows buffered data in the communications link to be effectively transmitted to

the other modem before the modems disconnect. Enable this feature if your application does not ensure a complete transfer of data before the modems disconnect.

•The default Answer option is country-specific. Refer to Appendix C to verify that this option is appropriate for your application.

•In Option Set 4, the default option for ACU Select=None. If you want an ACU to operate the modem, select an ACU and a data format.

•If you do not use theAT ACU to send commands to operate the modem, customize the DTE port as follows:

—Set the modem’s DTE rate to match the asynchronous DTE’s rate using DTE Rate (AT*DE, TERMINAL OPTS category).

—Set the modem’s parity to match the parity set in the asynchronous DTE using Parity (AT*RP, ACU OPTS category).

—Set the modem’s character length, using Char Length (ACU OPTS category) to match the character length in the asynchronous DTE.

(Refer to Appendix A for parameter and setting descriptions.)

•In Option Set 4, the modem is set for XON/XOFF (software) flow control. If your application requires hardware flow control, change the Flow option (AT*FL, TERMINAL OPTS category).

•If the DTE does not provide DTR, the modem will not automatically answer an incoming call. Set DTR=High (AT&D, TERMINAL OPTS category).
