Plus, this operation worked flawlessly on many drivers. \r\n\r\nIt is worth noting, that on SIMH V.3.9, some canonical processing took place with tabs and spaces. However, the copy was perfect in that it would compile without error.  Nevertheless, the paste operation was not an exact copy under SIMH 3.9, but it was close enough.  Only tabs and spaces on SIMH V3.9 would be changed during a paste operation such as this.   \r\n\r\nThe bottom line:  Under SIMH 4.0 Beta, I am unable to complete a paste operation as nearly all characters are dropped, excepting about 275 bytes.  Smaller paste operation (under the ~256 bytes seem to work fine.)   \r\n\r\nI have tried various incantations of modem control, etc with no success.   \r\n\r\nI want to be clear that the KL and DZ devices work beautifully for the most part.  The output always seems fine under SIMH 4.0.  But. input processing (such as pasting) no longer works like it did in Version 3.9.   \r\n\r\nOf course, all of this could be a simple misconfiguration on my part.  But, until this gets reviewed by the team here, it does seem like a potential defect.  \r\n\r\nBelow you will find the build information requested from the README.md file.  I would like to add one point:  The SIMH software is an amazing gem of software engineering.  For years, I have read every vintage UNIX manual I could get my hands on.   However, I was only left to imagine.  SIMH has brought my imagination to life.  As each day passes, the value of SIMH increases.  100 years from now, SIMH (or its progeny) will be used to demonstrate the dawn of automation.  I thank each and every contributor to SIMH.\r\n\r\n\r\nPDP-11 MACHINE V4.0-1 delta 1 Production  (Local Port, native V4.0 Beta Code)\r\n        Simulator Framework Capabilities:\r\n                32b data\r\n                32b addresses\r\n                Ethernet Packet transports:PCAP:NAT:UDP\r\n                Idle/Throttling support is available\r\n                Virtual Hard Disk (VHD) support\r\n                Asynchronous I/O support\r\n                FrontPanel API Version 1\r\n        Host Platform:\r\n                Compiler: GCC 5.2.0\r\n                Simulator Compiled: Oct 29 2015 at 22:38:50\r\n                Memory Access: Little Endian\r\n                Memory Pointer Size: 64 bits\r\n                Large File (>2GB) support\r\n                RegEx support for EXPECT commands\r\n                OS clock tick size (time taken by msleep(1)): 2ms\r\n                OS: Darwin corky 15.0.0 Darwin Kernel Version 15.0.0: Sat Sep 19 15:53:46 PDT 2015; root:xnu-3247.10.11~1/RELEASE_X86_64 x86_64\r\n\r\n        git commit id: 9ee290ac\r\n"},"comment":{"url":"https://api.github.com/repos/simh/simh/issues/comments/158649020","html_url":"https://github.com/simh/simh/issues/246#issuecomment-158649020","issue_url":"https://api.github.com/repos/simh/simh/issues/246","id":158649020,"user":{"login":"WILLIAMCORCORAN","id":15604988,"avatar_url":"https://avatars.githubusercontent.com/u/15604988?v=3","gravatar_id":"","url":"https://api.github.com/users/WILLIAMCORCORAN","html_url":"https://github.com/WILLIAMCORCORAN","followers_url":"https://api.github.com/users/WILLIAMCORCORAN/followers","following_url":"https://api.github.com/users/WILLIAMCORCORAN/following{/other_user}","gists_url":"https://api.github.com/users/WILLIAMCORCORAN/gists{/gist_id}","starred_url":"https://api.github.com/users/WILLIAMCORCORAN/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/WILLIAMCORCORAN/subscriptions","organizations_url":"https://api.github.com/users/WILLIAMCORCORAN/orgs","repos_url":"https://api.github.com/users/WILLIAMCORCORAN/repos","events_url":"https://api.github.com/users/WILLIAMCORCORAN/events{/privacy}","received_events_url":"https://api.github.com/users/WILLIAMCORCORAN/received_events","type":"User","site_admin":false},"created_at":"2015-11-21T14:38:49Z","updated_at":"2015-11-21T14:38:49Z","body":"Hi Mark,\n\nSure.  Now, you will want me to use the first link you gave me for the master.\n\nNext, I remember now one of the anomalies I discovered with the host sleep() in 3.9.  When the system woke back up, system processes like swapper would have huge amounts of CPU time on then to where it overflowed and was a negative number.  You could see this with a ps.   \n\nTruly,\n\nBill Corcoran\n\n> \n"}}
