Right-shift + cursor-right starts the (Kermit) Server mode

Sorry, I meant (press and hold) right-shift + cursor-right.
On the 50G the Kermit server mode can also be started by [APPS] [2. I/O functions] [6. Start Server].
Either way the 50G displays "Awaiting Server Cmd." but obviously doesn't receive any commands send from the PC.

My configuration on the 50G is as follows:

Code:

Port: USB     Type: Kermit
Fmt: ASC   Xlat: ->255  Chk: 3

This worked before and actually is still working when connecting to an older PC running the good old Ubuntu 12.04.

If someone wants to test this on his own hardware, here is the procedure for Ubuntu/Debian systems (to be executed in a terminal window):

(1) Make sure you have installed Kermit:

Code:

sudo apt-get install ckermit

(2) Add your username to the dialout group:

Code:

sudo usermod -a -G dialout $USER

(3) Logout and log in again, or simply restart your computer.

(4) Connect your 50G with the USB cable to your PC an turn it (the 50G) on.

(5) The "dmesg" command should show something like the following:

Code:

[  308.411735] usb_serial_simple 3-1:1.0: hp4x converter detected
[  308.412374] usb 3-1: hp4x converter now attached to ttyUSB0

(6) Check if the device is really present:

Code:

ls -l /dev/ttyUSB0

Code:

crw-rw---- 1 root dialout 188, 0 Apr 15 08:05 /dev/ttyUSB0

(7) Set the 50G into Kermit Server mode by press/hold right-shift + cursor-right.
It should display "Awaiting server cmd." but not "Xmodem Server".

(8) Start "kermit" on the PC and enter the following commands:

Code:

set modem type direct
set prefixing all
set port /dev/ttyUSB0
set speed 9600
set carrier-watch off
set flow none
set parity none
set block 3

remote directory

If everything is working well, the busy indicator on the 50G should start blinking and after a few seconds you should see the contents of your current 50G directory in the kermit window.

But most likely Kermit hangs (as in my case) and nothing happens. You may need to turn off the 50G to force Kermit to disconnect.

If someone gets it working on his hardware or spots an error in this procedure, please let me know!

Thanks in advance!
