    The IBM 5271 System Units are orderable as standard models. Each includes a power cord and the Guide to Operations. For Models x3x, x5x, x7x the Hardware Maintenance and Service Manual is separately orderable from Mechanicsburg as a supplement to the IBM Personal Computer Hardware Maintenance and Service Manual. (The IBM 3270 PC Maintenance Information Manual (SY27-2567) is included only with Models 002, 004, 006, 024, 026.)

    The 5271 models 031, P31, P30, 051, P51, P50, 071, P71 and P70 require 3270 PC Control Program Version 3.0. The 5271 models x3x, x5x, x7x, require IBM PC DOS Version 3.1 or 3.2.

    Performance

    When a 3270 Personal Computer is connected to a local channel unit (3274-31A, -31D, 41A, -41D) in Control Unit Terminal mode, an increase in system response time of about 100 ms may be experienced when running base data stream applications when compared with a 3278 Display.

    During file transfers in Control Unit Terminal mode, a noticeable impact on the response times of other terminal connected to the same local channel unit may be experienced. The duration of the delays is dependent upon the file size, frequency of transfers, type of control unit or modem, and customer setup. The 3270 PC File Transfer Licensed programs transfer files in 2000-byte blocks to minimize the impact on the network that large file transfers might have.

    The multiple logical terminal facility of the 3270 Personal Computer allows the user to designate up to four terminal addresses in a single 3270 Personal Computer. This requires one physical port in the 3274 Control Unit. When planning installation of the 3270 Personal Computer consideration must be given to the number of logical and physical addresses that are to be used compared to the maximum number of addresses and ports that are available. The number of addresses and ports available is dependent on the model 3274 and the method of system attachment.

    When the 3274 has 3270 Personal Computers attached that are operating in Distributed Function Terminal mode, Table B specifies the maximum number of 3270 Personal Computer or other logical terminals that can be attached to the 3274.
