Changed method in which JMODEM acquires memory. Since many BBS systems
seem to be messing with DOS's internal memory allocation scheme, it
isn't practical to assume that JMODEM was properly loaded. Therefore,
a DOS call is made to free up all memory allocated to JMODEM. This
will fail and cause an abort if JMODEM was not loaded by the parent
properly. Next a DOS call is made to allocate the memory JMODEM needs
for buffers. This will fail if JMODEM was not loaded above memory that
is currently in use. In both cases, error messages are printed that
disclaim any responsibility.
