[HP48] Kermit setup

[Hiwi]

I am using kermit data communication since years and there are still new builds from time to time and despite of c source you can download executables as well for nearly every platform.
The last build was from December 2022.

The implementation of the kermit protocol on the HP48 is not the fastest but works reliable.
If i have to transfer big libs i am using xmodem from teraTerm and a xmodem programm on the HP48.

But in daily use i like Kermit.
I am using an usb to serial adapter and an homebrew cable for the HP48.

The setup is simple, just extract the distribution zip file on your local storage.
I does not work out of the box you have to make some entries in the k95custom.ini file:
Put these lines at the end of the file

Code:


set port 4 ; serial com port on unix machines that is /dev/tty... or /dev/cuser...
set speed 9600          ; serial port speed
set carrier-watch off   ; no carrier detection, this is for modems only
set modem type direct   ; no modem direct serial line
set flow none           ; no flow control
set parity none         ; 8 data bits, no parity
set control prefix all  ; prefix all control chars, may be unprefix all adds some speed
set file type binary    ; better to ste this, since otherwise LF/CR may be a problem
set send paket-length 64 ; HP48 can only handle this small packets 
set terminal pcterm   ; optional
set terminal type tty ; optional, depends on the host

Now make pysical connection set HP48 to servermode, type K95.exe, connect with ALT-X go back to command console (ALT-X)
Transfer files with send file.xyz

The other way is to setup server, in command console type server
on HP 48 send file with lib I/O transfer...
