-Several sites also refer to mods for up to 115200 bps speeds (on all ports? Link?). Amiga.resource.cx also has a photo of a board with a title "Rev 6 board with RTS/CTS handshake mod". Another modification is to replace the 1.84 Mhz oscillator with a 3.68 Mhz one. This doubles the baud rates but the software won't know about this so the user must keep this in mind when using the board.+Several sites also refer to mods for up to 115200 bps speeds (on all ports?

Up to five boards are supported (probably a limitation of the number of Zorro slots in any available machine). If several A2232 boards are installed, the second board'​s unit numbers are 9-15 and so on.

 +Probably the main selling point of the A2232 was the ability to connect several serial terminals to an AMIX machine. To start a login shell at any of the serial ports, use pmadm: **pmadm -e -p serial -s ql00** This enables shell in the first port at the default speed of 9600 bps (defined as the '​serial'​ preset in /​etc/​screendefs)
