February 1, 1991 ACCESS SERVER and MODEMS Access Server supports asynchronous transmission speeds up to 19.2 Kbps using dial-up modems such as the Hayes Smartmodem and modems with error correction, data compression and/or V.32 capabilities. A list of certified and recommended modems is included in this document. Error correcting modems are strongly recommended. For the best Access Server/modem relationship it is recommended that you have the most recent version of Access Server and the most up to date PTF (at the moment version 1.01 and PTF 238) The Access Server and ONLAN menus provide a list of modems which have been tested with Access Server and for which scripts have been written. It can be very difficult (and sometimes impossible) to successfully use a modem which is not specifically listed. 1. Access Server currently supports the following modems: Version 1.01 as shipped:Version 1.01 of Access Server, contains a few modems not included with version 1.0. ONLAN/PC was not updated. In order to update ONLAN/PC, copy the NASMODEM.CNF file from Access Server Version 1.01 diskette to the ONLAN/PC diskette and rename the file ONLANMDM.CNF.

However, it is often possible to get such modems to work with Access Server if the V.42 feature is turned off. V.32 and MNP US Robotics V.32 and MNP modems work properly with Access Server. Other "High End" modems with features such as V.32 and MNP which may work with Access Server tend to switch to such "feature" settings when communicating with exact duplicates of themselves and then can not communicate/connect with other modems unless manually reset. "HAYES COMPATIBLE" Both Access Server and ONLAN provide the user with the choice of "Hayes Compatible". This provides only a 1200 BPS connection and is not recommended as a choice unless all other options have been tried. At speeds above 2400 bps the term "Hayes Compatible" has little meaning. MULTIPLEXERS Certain AT&T, MultiTech, and Racal-Vadic MUXs have been certified. Set the MUX configuration to control carrier with DTR. If using a MUX configure Access Server for "Direct Connect" and for a specific baud rate (not AUTO BAUD). DIRECT CONNECT In addition PCs and/or ASCII terminals can be directly connected to the Access Server through a RS-232 null modem cable. Distances greater than the RS232 specification of 50' require a modem or line driver. Configure for a specific baud rate (not AUTO BAUD).
