CP/M Kermit Experiences

Postby TRS80 on Thu Sep 06, 2012 11:06 pm

I managed to get Kermit 4.11 on the Home Brew CP/M board and have it mostly working with C-Kermit to tranfer files from my Macbook.

"Mostly working" means that it will transfer files OK but very slowly with a high error count. I am running my serial connection at 115200 with RTS handshaking. Setting a received packet length to 64 was necessary to get it going but I am hoping I can get a bit more speed out of it.

I suspect the problem is due to the serial port being shared between the terminal/console and the kermit transfer so "status" messages are being sent which cause retries/etc so will need to get a serial port monitor on the connection to see what is being sent. I have set the Terminal parameter to Quiet at the CP

Terry - I know you got this going on your Kaypro where the serial port is different from the terminal/console. Do you see transfer errors at all? What version of Kermit do you use on the Host (i.e less vintage... where you are copying from) machine? Are there are particular configuration settings you use?

Anyone else got any experiences with this?


Wanted: S-100 Bus components - please PM me if you have any. They don't even need to work!

I used Windows XP Hyperterminal on a PC and Kermit on a Kaypro for file transfer. It was a while ago...

Here is some experience with PC ---> Kaypro transfers . See the section called "Replacing the MS-DOS intermediary with serial transfer".

..and here is the discussion regarding teething problems with Kermit which I manage to crack eventually.

Hope this helps!
