[comp.os.cpm] Kermit for Kaypro1

pvpullen@CRDEC-VAX2.ARPA ("Paul V. Pullen") (02/06/88)

I need some assistance from a Kermit expert in getting a properly assembled 
and loaded Kermit for my Kaypro1.  I have all the asm files, and have tried
to reassemble the machine dependent code to come up with a working Kermit.

I find that if I try to download a file in excess of 116 packets, the Kermit
cannot swallow the code at the same time it is writting to the disk.  The 
error displayed on the screen is:

?unable to rec data
Failed  

B0 KERMIT >>

I am using version 4.05 of Kermit, and have C-Kermit in our base VAX down-
loading files.  As long as file size is small enough, the program does fine.

Any assistance would be greatly appreciated.

Try setting setting Kermit's buffer size down to 8 or 4 K.  CP/M Kaypros have
very slow disk i/o, particularly writes.  It actually writes each physical
(512 byte) sector 4 times!  The ROM enhancements (e.g. Advent TurboROM)
eliminate this.  The TurboROM actually provides 4 times faster writes and
2 times faster reads.
