Introduction
Communications (WAN) Functions No Longer Supported
The following functions are no longer supported on current AS/400 product line WAN
hardware (such as the #2609 EIA 232/V.24 Two Line Adapter, the #2610 X.21 Two Line
Adapter and other, older adapters). They are not supported on the #2720 PCI WAN/Twinaxial
IOA, the #2721 or #2745 PCI Two-Line WAN IOA, the #2699 Two-Line WAN IOA, or the
#9771 Base PCI 2-Line WAN with Modem.
• X.21 switched interface (X.21 leased support)
• X.21 Shorthold mode
• V.25 2 port autocall. This is the protocol used to auto dial on switched connections
using modems that require a second port dedicated to the dial function. Do not
confuse this with V.25bis, which is the current day autocall protocol that sends dial
commands over the same port used for data. V.25 bis itself is supported.
• Asynchronous communication speeds of less than 300 bps.
• Data Rate Select signal on the EIA 232/V.24 interface. This function is used by some,
older 2400 bps modems to reduce the speed to 1200 bps.
