You are probably using the last freely distributable JRcomm.  However,
a more recent one available to registered users has the ability to do
asynchronous writes to floppy; ie, it will save one block while receiving
another.  This should alleviate your problem.

BTW, JRcomm is a *great* terminal program, especially now that it has
ansi and vt100 emulation, etc.  Its well worth the small price he asks
for it.  The lastest one (0.99) is better, faster, and more configurable
than most commercial terminal programs I've seen.  Way to go Jack!
