File transfert with kermit

[Olivier Lécluse]

Hi. Im am new to this group. I have just finished assembling my IMSAI8080 replica. This is really a great kit. I have also installed the imsaisim software from z80pack on my PC (linux). This is a great piece of software.

My question is : how to transfert a file from the PC to the IMSAI and vice versa.

I have managed to do this via dsk and cpmtools : the following command does the trick

cpmcp -t drivec.dsk my_file  0:

then I transfert the dsk on the IMSAI and it is OK.

I was looking for another solution. I saw this conversation and I tried to get this work

https://groups.google.com/g/imsai8080esp/c/FGJAe_DgwiM/m/H0NgKUxQAgAJ

but with little success :

Everything works fine until I try to send the file. I am probably missing something here.

This is the steps I follow :

1. on Linux :

(/home/me/) C-Kermit>set host * 8080
Binding socket to port 8080 ...
Listening ...
Waiting to Accept a TCP/IP connection on port 8080 ...

2. on the IMSAI :

b:kermit

Kermit-80   0C:>Set port UC1
Kermit-80   0C:>Connect[Connected to remote host.  Type Control-\C to return;
 type Control-\? for command list]

I then type : ATD192.168.1.60:8080

3. on linux

I see the conection established :

Reverse DNS Lookup... (OK)
imsai8080.local connected on port 8080
(/home/me/) C-Kermit>

then I type :  send /protocol:xmodem test.pas

 Sending /home/me/test.bas, 46 blocks:

Give your local XMODEM receive command now.

4. on the IMSAI

rx test.pas

but I can't get a prompt or anyhing to type the receive command. CTRL-C does nothing. The console is stuck and I have to do a reset.

If I type "C" I see the beginning of the file and an error on the Linux :

Retry 0: Timeout on sector ACK
Retry 0: NAK on sector

Do I miss something ?

Thanks

Does this help?

Thank you for the link. It is very useful.

Unfortunately, I am still stuck at the same place : Just after I connect the imsai to the PC with ATD, I can't get the prompt back. The guide says "Press Ctrl and *, followed by *C to return to the Kermit command prompt." but this doesn't work. I am using a french keyboard, maybe the keys are different on azerty ?

The default escape of kermit is CTL-\, so you need to type CTL-\ followed by c.

On many keyboards other than US entering CTL-\ really sucks. You can change

the escape character with 'set escape', I usually use CTL-A.

The I made a video showing how I transfer files between the IMSAI (PC emulation)

and a VM running MWC COHERENT:

Also it is more comfortable to set the host kermit right into server mode:

set host /server * 8080

Then on the connected CP/M kermit you can do:

remote dir                         - show hosts directory

remote cd somedir           - change directory on the host

send filename                   - send a file to the host

receive filename               - receive a file from the host

Don't forget to hangup the modem connection after done, won't happen magically ;-)

Connect to the modem again: connect

Type +++ to get into command mode and hangup with ATH.

Thank you very much. This is exactly what I needed.

Everything is working great.
