Mike,
A couple thoughts:
1. DUART has handshake signal that I brought to the serial connector but didn't use because gkermit is fast enough without hardware handshake. I know the handshake does work. You may be able to run ZMODEM with hardware handshake at higher baud.
2. I have a quad serial board that works with CB030's expansion bus. It is based on OX16C954 where transmit/receive channels are backed with 128-byte FIFO. I can send you a Quad serial board if you like to try it. https://www.retrobrewcomputers.org/doku.php?id=builderpages: plasmo:quadserplcc
