IBM Twinax-Terminals Overview
|This article isn't finished yet or needs to be revised. Please keep in mind that thus it may be incomplete.
Reason: Complete table
IBM created numerous Twinax-Terminals in the course of the lifetime of the systems supporting Twinax, and the 5250 data stream:
It's important to know that the 5250 data stream supports only two display modes:
- 24 lines, 80 characters each, programmatically named *DS3,
- 27 lines, 132 characters each, programmatically named *DS4.
The following table lists (once) available terminals, and features.

- IBM 5250 in Wikipedia
- Position 1 of lines is almost always unused, because the invisible display attribute character needs one position of space. This is also the reason that different elements, or the same element with different display attributes need one space between them.
- Example: IBM 5294, or 5394. This is a twinaxial device to share a leased or switched line with many twinax devices.
