Subject: MODEM Hiccups

        In trying to move some files from the ECLB TOPS-20
system, I have encountered two problems:

                1. Persistent aborts after 60-100 records (but
always at the same record) in CRC mode

                2. Consistent abort for "Bad Header" at record
255 in checksum mode (which suggests to me that modem is not
rolling over beyond 0FFH).

        On the receiving end, have been using an Osborne 1
running MDM791, and an H-89 using MODEM901, both at 300 baud.
Problem occurs in same place on both.  Files were being sent with
binary output set on TOPS-20.

        Has anyone else encountered this?  I didn't until two
days ago; has anything changed?
