+====== Installing Kermit for bulk file transfers with ROMWBW ======
+The following documents my attempts to use Kermit for bulk file transfers. Initially using a Windows Kermit implementation and then using Teraterms Kermit file transfer facilities. Teraterm turned out to be the better program in the end but both suffered very slow transfer speeds.
+Download and install on your windows machine:
+Windows Kermit Program http://kermit.wwarthen.com/files/v085/kw32v085.zip
+Tera Term terminal program https://osdn.net/projects/ttssh2/releases/ https://osdn.net/projects/ttssh2/downloads/72009/teraterm-4.105.zip/
+You may need to change your security permissions of the Kermit install directory C:\Program Files\KermWin so you have full access to allow received files to be saved.
+====== Preparing the CP/M version of Kermit ======
+Download to your windows machine:
+Kermit CPM archive http://www.columbia.edu/kermit/ftp/archives/cpm80.zip
+Extract and transfer cpsker.hex, cpvgen.hex, mload.hex from the cpm80 archive to your CP/M machine.
+<code code>
+H>dir *.hex
+  |  MLOAD   .HEX  |  CPSKER  .HEX  |  CPVGEN  .HEX
+</code>
+Convert the mload.hex file to an executable file.
+<code code>
+H>b:load mload
+FIRST ADDRESS 0100
+LAST  ADDRESS 0BBC
+BYTES READ    0ABD
+RECORDS WRITTEN 16
+</code>
+Create the generic kermit executable:
+<code code>
+H>MLOAD KERM411=CPSKER,CPVGEN
+MLOAD ver. 2.5   Copyright (C) 1983, 1984, 1985
+by NightOwl Software, Inc.
+Loaded 26086 bytes (65E6H) to file H0:KERM411.COM
+Start address: 0100H  Ending address: 73C7H  Bias: 0000H
+Saved image size: 29440 bytes (7300H, - 230 records)

+On Windows, start Tera Term and connect to your CPM machine using the primary serial console and start Kermit:
+<code code>
+H>kerm411
+Kermit-80 v4.11 configured for Generic CP/M-80 with Generic (Dumb) CRT Terminal type selected
+For help, type ? at any point in a command
+Kermit-80   0H:>
+</code>
+Setup Kermit
+<code code>
+Kermit-80 0H:>set file-mode binary
+Kermit-80 0H:>set port UC1
+</code>
+If you need to change the drive to send or receive files use:
+<code code>
+Kermit-80 0H:>set default-disk I:
+</code>
+On Windows machine Start kermit:
+Setup your communications serial line to match your CP/M machine under Configure>Communications
+Kermit only supports ports COM1:-COM4: You may need to go into device manager and change the assigned port to put it in this range.
+Open a session under Session>Connect
+Sending files from CP/M to Windows
+In Windows Kermit select Kermit>Receive
+In your Tera Term (CP/M) windows type //send// ////filename//// or //send //wildcard////
