Hello,
 
I have found the fix to the bug in with the TRANSMIT command in version 4.09 of
kermit.  The bug is in the file CPSUTL.ASM. The problem is that subroutine
INBUF: is pre-decrementing the byte count by 1, (decrementing an assembly
generated constant) causing the last character of each record to be ignored.
 
The line at fault was a few lines after label inbuf2: and read
 
        mvi     a,bufsiz-1      ; Number of bytes in buffer (pre-decremented)
 
this should be corrected to
 
        mvi     a,bufsiz        ; Number of bytes in buffer.
 
This bug only shows when files to be send via TRANSMIT are greater than 128
bytes.
 
 
The pausit: routine in the same file is also missing a return statement.
The cpsker.hex file does not seem to have this problem, but the source
file does not have the return listed in the (corrected) code fragment below:
 
        jz      pausi1          ; loop until a key has been pressed.
        ret
 
I hope this can help someone.
