The version on our system is '1.44', whatever the date works out as.  When
I transfer files, my ZCOMM detects the 7-bit path, and tells the other end
to switch to 7-bit mode.  In extreme cases, the -e option on either end will
force the transfer to take place as if the line were 7-bit (I know, the
throughput slows from 230cps to 180cps at 2400 baud!).  I am using the 
latest ZCOMM (March 90).
