    Some months ago I sent to this group a note concerning my Kermit68K,
a portable Kermit program for machines based on the 68xxx microprocessors
family. In that note I was looking for wizards of the various OS running
on the 68xxx willing to implement Kermit68K on different machines.

   Now the OS9 version of Kermit68K is ready and is distributed by Columbia
university, several people sent me messages saying that it works with no
problems (a good result for a 1.0 release).

   I've received a lot of requests for a CP/M-68K and a VERSADOS version of
the program, but, unfortunately, no help offers from experts of this operating
systems, so I'm writing the system-dependent module for CP/M-68K by myself.
I've started this job the 3 August and just now Kermit68K/CPM works rather
well. Since all what I know of CP/M-68K is what I've learned this month
by reading the Programmer's Guide (the only CP/M-68K manual I've), I need
some help from CP/M-68K experts out there.

Current problems (by sure due to my poor knowledge of the OS) are:

1) By reading the manual and looking at my BIOS sources it seems impossible
   to check the status of the auxiliary input device, that is the system
   services handler, once called, doesn't return until a character is received.
   If this is true I can't implement input timeouts in a portable way,
   I need a small serial driver for each machine. Am I wrong ?

2) The Search for First and Search for Next system services seem don't
   care of the passed FCB content, any directory entry is returned regardless
   of the file name and type I've written into the FCB. Should I do
   the filename matching by myself ? In this case has anyone a suitable
   assembly language routines ?

People interested in receiving the current sources shouldn't hesitate
to contact me at any time. Except for the aforecited problems Kermit68K/CPM
is working well transferring binary and text files correctly and efficiently.
Thank in advance for your help and suggestions.

              Roberto

P.S. I've done all the job in 10 working days (including the manual
     reading, without prior knowledge of the OS), any willing VERSADOS
     (or other OS) implementor now ?
