+To transfer files to and from my Grant Searle based
+CPM computer, I started using DOWNLOAD.COM and Grants
+windows application for creating compatible "packages".
+But, this was tedious, and very error-prone. So I looked
+for a better solution, and found one that works for me at
+http://oldcomputer.info/others/z80sbc/index.htm
+
+Using the C-Kermit package linked there, along with
+standard ckermit on Linux, I have a much more reliable
+and convenient way of getting data to and from the CP/M machine.
+
+I use the second serial port of the CP/M machine's SIO/2
+attached to a USB serial adapter on the Linux host.
+
+A typical session, involves typing up the assembly code,
+then using the crasm assembler to produce an Intel HEX file.
+The Hex file gets transferred to the CP/M system "raw":
+
+On the CP/M side I start Recieving of file using:
+D> KERMIT
+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   0D:>SET PORT PTR
+Kermit-80   0D:>R
+
+
+On the Linux side I set up the Sending using:
+jonlan@JL-X260:~/Code/z80cpm$ kermit
+C-Kermit 9.0.302 OPEN SOURCE:, 20 Aug 2011, for Linux+SSL+KRB5 (64-bit)
+ Copyright (C) 1985, 2011,
+  Trustees of Columbia University in the City of New York.
+Type ? or HELP for help.

+(/home/jonlan/Code/z80cpm/) C-Kermit>s file.hex
+
+
+Finally, back on the CPM host, the HEX file is converted to a
+loadable COM file using the CP/M 2.2 LOAD.COM utility:
+
+D>A:LOAD FILE
+
+
+Cut-and-paste friendly settings for C-Kermit:
+CP/M side
+
+set port ptr
+
+Linux side
+
+
+set modem type none  
+set line /dev/ttyUSB1
+set carrier-watch off
+set speed 115200
+set flow rts/cts
