Hi,

I am trying to use Kermit for the first time on an Advantage and am stuck. I installed it using help here:

http://www.z80.eu/kermit.html

I first transferred MLOAD.HEX using PIP and Putty (pasting text in with a right click), with an SIO card in the board 1 slot. This only seemed to work at 1200 baud, as this speed seems to be coded into the CP/M BIOS.

This seemed to work so I copied CPVADV.HEX and CPSKER.HEX again using PIP. The later I had to split into 3 smaller files, as otherwise disk activity occurred mid way through and as I had no flow control set up, and this would lead to some lines being missing.

Anyway, I ran KERM411.COM, but am unsure whether this can use SIO board in slot 1 or 0. The Kermit SET PORT 0 or SET PORT 1 command gives an error (Not implemented).

The SET SPEED 1200 command was accepted so I assuming 1200 baud.

On the Windows 7 PC I am trying to use teraterm 4.84 (4.85 came out today but it wouldn't install).

I set the PC to receive a Kermit file (on COM3: 1200 baud) and then tried sending a file from the Advantage KERM411. Both ends just sit there, and the Interfaker(RS232 breakout box) LEDs don't flash.

I looked on ftp.columbia.edu for some of the source files for the Advantage, but could only find the .HEX files.

Can anyone help please?

Regards,
John
PS - Once working I would be willing to copy KERM411.COM to floppy via post with any other Advantage owner.

PPS CP/M PIP command was in form:
PIP CPSVADV.HEX = RDR:

PPPS Since rule 1 of debugging is know the system, one thing I can try is set up another PC with Teraterm and try Kermiting files between them. Not used Kermit for years, probably was on MSDOS 3!

Your URL doesn't seem to work.

Hi, I am the web site owner (z80.eu).

For a bootstrap of "kermit" on a CP/M computer, you can take two .hex files for concatenating them with LOAD (MLOAD). They will converted back to binary in the same procedure.
The main file is CPSKER.HEX, the appropriate machine dependant file for a Northstar is CPVADV.HEX, so the load command looks like MLOAD KERM411=CPSKER,CPVADV.HEX and will generate KERM411.COM.

Thanks, sorry for the late reply, I wrote the following blog back in December but forgot to add a link from this forum thread:

http://www.vintage-computer.com/vcforum/entry.php?484-Installing-and-running-Kermit-under-CP-M-on-a-Northstar-Advantage

I subsequently have sold the Advantage, next project is to run Kermit under CP/M on a Zenith Z-100 so the above will be the basis of that little job.
