You may want to pick yourself up an rs-232 interface for your SX=64, the
kinds that allow you to use any rs-232 modem.  Hook that up to your SX and
then run a nulled cable from your PC to the SX.  Then you can run Procomm
on your PC and a terminal program that supports xmodem on the SX.  From
there everything is a breeze.  I use this same sort of setup to use my
C=128 as a terminal on my 386.  (can only use 2400 baud max, but oh well)

You probably could get the modem trick to work, but as I remember, the
TeleLearning modem is 300 baud and using my method you can use 2400.  

Hope this helps...
