The IBM Personal Computer (PC) ANR Adapter card and its support software were designed to make an IBM PC appear as an IBM ANR (3277) terminal to a host ANR controller (IBM 3272 or 3274). Thus, the IBM PC can be used as any other interactive ANR terminal for communications and interactions with a host system. The IBM PC however, with its local processing and data storage capabilities, makes it useful as a remote work station for selective local processing. This latter capability is enhanced if large quantities of data can be transmitted from the host to the IBM PC at relatively high data rates. The IBM PC ANR Adapter cards have a problem that causes data to be lost when contiguous blocks of data are transferred from the host to the IBM PC.
