Hello!
I have router with HWIC-8A . it’s very strange HWIC. One Part async interface have DSR=up without any attached cables and modem, other part have all signal DOWN. All Async lines not config.
Async0/3/0 is down, line protocol is down
Hardware is HWIC-Serial
…
DCD=down DSR=down DTR=down RTS=down CTS=down
Async0/3/1 is down, line protocol is down
…
DCD=down DSR=up DTR=down RTS=down CTS=down
Async0/3/2 is down, line protocol is down
…
DCD=down DSR=down DTR=down RTS=down CTS=down
Async0/3/3 is down, line protocol is down
…
DCD=down DSR=up DTR=down RTS=down CTS=down
Async0/3/4 is down, line protocol is down
…
DCD=down DSR=down DTR=down RTS=down CTS=down
Async0/3/5 is down, line protocol is down
…

Async0/3/6 is down, line protocol is down
…
DCD=down DSR=down DTR=down RTS=down CTS=down
Async0/3/7 is down, line protocol is down
