dtterm and Terminals Capable of Input and Output of UTF-8 Characters

The dtterm(1) and any terminal that supports input and output of the UTF-8 codeset should have the following STREAMS configuration:

head <-> ttcompat <-> u8euc <->  ldterm <-> eucu8 <-> pseudo-TTY

In this example, u8euc and eucu8 are the modules supported by the en_US.UTF-8 locale. Make sure you already loaded the STREAMS modules into the kernel as specified in the previous section.

To set up the above STREAMS configuration, use,strchg(1) as shown below:

system% cat > /tmp/mystreams 
ttcompat
u8euc
ldterm
eucu8
ptem
^D
system% strchg -f /tmp/mystreams

When using strchg(1) , be sure you are either root or the owner of the device. To see the current configuration of STREAMS, use strconf(1) as shown below:

system% strconf
ttcompat
u8euc
ldterm
eucu8
ptem
pts
system%

To revert to the original configuration, set the STREAMS configuration again as shown below:

system% cat > /tmp/orgstreams
ttcompat
ldterm
ptem
^D
system% strchg -f/tmp/orgstreams
