The 2-port Asynchronous PCI adapter
Technote (FAQ)
Question
My system only has two native vty ports available. I was told that there is a 2-port Asynchronous PCI adapter I can purchase for my system. Do you know the part number?
Answer
The IBM 2- and 4-Port RS-232 Serial Adapters
There are actually two solutions (answers) available to this question. The IBM 2- and 4-Port RS-232 Serial Adapters. These adapters are an easy way to add additional, full function EIA-232 ports to your system without the need for purchasing larger capacity serial adapters; e.g. IBM 128-port EIA-232 adapter.
2-port Asynchronous EIA-232 PCI adapter
The 2-port Asynchronous EIA-232 PCI adapter - IBM part number (FRU): 64P1243) provides connection for two (2) asynchronous EIA-232 devices. Ports are programmable to support asynchronous protocols over an EIA-232 interface at line speeds up to 128 Kbps. The adapter provides the following functions:
