All interfaces were made available, 5 in Cyclone IV versions and 3 or 4 in Cyclone II versions
The monitor will accept input from device 1-4 (if available), typically TTY1, VDU, TTY2 and TTY3. No TTY4, because CP/M 2 and derivatives only allow for 4 devices in the IOBYTE.
This device will then become the default console in CP/M.
Off course the BAT: assignment loses its meaning. the STAT.COM utility was changed so that the physical console devices now read TTY: CON: UC1: UC2:
In Cyclone IV versions CON: and LST: select interfaces 1-4 and RDR: and PUN: select interfaces 1, 3-5
CP/M 3 and derivatives allow for more physical devices. The 5 logicical ones (CONIN, CONOUT, AUXIN, AUXOUT and LIST) can be assigned to each of the 5 physical ones with the DEVICE.COM utility. 
This tool can also assign a baudrate to a physical device, but the values are not accurate.
Therefore DEVICE.COM was modified to accept and display the right ones (mostly), as long as they are 1200,2400,4800,9600,19k2,38k4,57k6 and 115k2. 
Others are still possible, but they map to one of those mentioned. Also the HELP.COM tool was modified to reflect this. 
CP/M 2 and derivatives have no native tool to modify baudrates. A tool called SETBAUD.COM is provided to do this.
