;  We use a loop here so as to open and close the session log
;  once a minute. This ensures that data is written to disk and
;  not held in a buffer and minimizes the amount of data lost in
;  the event of a power failure.
;
;  The filename in which data is recorded is of the form:
;        YYYYMMDD.cdr
;  where YYYY - the year
;          MM - the month
;          DD - the day
;  To do this requires the use of MS-Kermit 3.12 or later because
;  it is done using the \v(ndate) variable.
;
;  Because the filename is the numeric date and the file is
;  opened and closed every minute, Kermit will start recording in
;  a new file every day. Be sure the clock on the PC is set to
;  the correct time-of-day!

;  data in its buffers to disk first.

You might try
a) switching to raw mode prior to the 'cat' command, or
b) switching the /dev/ttyS0 'stty eof' character to the appropriate
    character for your serial feed.
