Abstract

This article describes a method of connecting an Intelligent Work Station (IWS) to a host computer over a dial-up voice grade telephone line. The method makes maximum utilization of the resources available on the IWS, the host, and the telephone line. Also, the method has error checking for data corrupted by telephone line noise. Release 1.1 of the IBM Information Network Personal Computer Information Exchange Interface (PC/IE) product implements this method to attach a Personal Computer to the Information Exchange product on the host for the purpose of electronic mail and file transfer. To minimize use of the telephone line, as much work is done offline as possible. This includes creating electronic messages, specifying files to be sent and received, creating destination lists, and browsing received messages.

This article describes a method of connecting an Intelligent Work Station (IWS) to a host computer over a dial-up voice grade telephone line. The method makes maximum utilization of the resources available on the IWS, the host, and the telephone line. Also, the method has error checking for data corrupted by telephone line noise.

To minimize use of the telephone line, as much work is done offline as possible. This includes creating electronic messages, specifying files to be sent and received, creating destination lists, and browsing received messages.

It then processes the list of stored requests. To perform each request, the IWS sends a formatted command to the host and gets a formatted response back. The IWS interprets these commands and responses to perform requested functions. The user does not participate in this activity. This is called the online unattended session. If a telephone line problem occurs during the online unattended session, the IWS will redial the tele...
