Help with xmodem over Ethernet Terminal Server/SunOS 4.0

[bbt!wgd at rti.rti.org]

Blah!  Here's the setup.  Sun 3/160, running SunOS 4.0.1 with yapt5.4
patch.  Terminal (actually a Mac or a PC) connected to a Bridge CS100
Ethernet Terminal Server, through which we log in to the Sun.

Problem:  Xmodem transfer attempts fail on any file that requires more
than 12 blocks (of any size, on this case either 128 bytes or 1024 bytes).
Does fine until block 13, which results in transmission errors reported at
the micro.  Happens for both IBMish PC and Macintosh.  

Note that file transfers ARE successful if done using the serial port.  I
transferred about 250K of stuff via modem at 1200 baud with NO problems at
all using xmodem and my Mac.

Has anyone experienced similar problems?  If so, what's the resolution?

Thanks.
