Subject: MEX batch transfer mode

Does anyone know what MEX is expecting when using the batch xmodem
transfer modes (ie sb and rb).  I have been trying to use it with the
Unix commands sb and rb which came from simtel20 in
pd:<unix.communication>x-ymodem.shar.1

MEX and sb/rb can't seem to agree on the exchange of file names. When
send/receiving a single file, they seem to work ok in crc/checksum
and 128/1024 combinations.  The unix version is 4.3BSD on a Vax 750.
rb and sb were compiled with cc -O -DV7 xx.c -o xx as per the
comments in the files for unix v7, 2.8 and 4.x.

Any descriprion of the file name exchange expected by MEX or
pointers to docs for it or y-modem (yam?) protocols would be
appreciated.
