I am unable to cu out via modem, due to /dev/term/00 blocking when
the rs-232 CD line (I assume) is low. How can I get the ttymon or whatever
to ignore this while hayes commands are being sent to the modem?  It
all works correctly when a terminal which holds CD and the other couple
handshake lines high is connected in place of the modem (but this is not
nearly so useful :-}.  The manual doesn't yield anything useful regarding
this.

I am using UHC SysV.4 Version 2 on a 386.

Thanks, and apologies for what must be an common question,
Andrew Herbert
