Diskette Sort
With the Diskette Sort feature, you can sort diskette records in either
ascending< or descending sequence. Up to six fields of not more than 64
characters can be sorted with the feature. You can create a new diskette file
containing the sorted records, or you can create a diskette file containing just
the sorted record addresses (address out sort).
Expansion Feature
The Expansion feature is a prerequisite for the Serial I/O Adapter and/or
Asynchronous Communications features.
Asynchronous Communications
With the Asynchronous Communications feature, the 5110 can transmit data to
a nd receive data from a host system. The 5110 uses the IBM 2741
Communications Terminal data link control and, thus, can communicate with
many systems that support the 2741 (start-stop) data link control.
With this feature you can:
• Enter data from the keyboard and transmit it to the host.
• Enter data from the keyboard and store it for printing, writing on tape, or
writing on diskette. Later, the data can be transmitted to the host from the
tape or diskette.
• Print the data that is transmitted to the host system.
• Write messages on tape or diskette that are received from the host system.
• Print data that is received from the host system.
• Inquire into host system data bases or program libraries.
The Asynchronous Communications feature transmits and receives data at
134.5 or 300 bits per second using the EBCD (extended binary coded decimal)
or correspondence code structure. The 5110 connects to an external modem
with a cable that meets the EIA RS232C/CCITT V.24 V.28 interface standard.
