Posted 24 Jan 2008 (edited) after banging the head around, I found a work around to have both No Protocol's RXD and TXD plus the convenience brought by Host Link commands. In CP1H Host Link mode, you can use SEND command if you would like to send some raw hex data as in No Protocol mode. Edited 25 Jan 2008 by jeenjang Share this post Link to post Share on other sites
