Product Overview
stopbits 1
speed 1200
Note: To allow an IOx application to control the serial port parameters (set baud rate, data bits, parity, stop
bits), you must use the "propagation" keyword as shown in the following example:
IR800#conf t
Enter configuration commands, one per line.
IR800(config)#relay line 1 1/5 ?
propagation
<cr>
IR800(config)#relay line 1 1/5 propagation
Virtual Serial Ports
Line 1/5 and 1/6 are the Linux serial ports viewed from IOS
line 1/5 1/6
transport preferred none
transport input all
transport output all
The physical and virtual ports are then linked by the following constructs:
relay line 1 1/5
relay line 2 1/6
• The serial devices, line 1/5 and 1/6, in IOS are instantiated in IOx as /dev/ttyS1 and /dev/ttyS2.
• The IOx serial device on the Linux host can then be exposed to an application container.
The port mapping from the physical port though IOS to the IOx would appear as in

Figure 16: Port Mappings
To switch Serial 0 from RS232 to RS485, the configuration is set in interface Async0. The RS485 half or full
duplex is set there as well. For example:
RS485 HALF DUPLEX - Serial 0 Only:
interface Async0 no ip address
encapsulation relay-line half-duplex
media-type rs485
Allow virtual serial port to control the parameters
