AR488 with HP1630D

[Vivis]

Hi all,
I have an HP1630D I'm trying to get an inverse assembler on. I've built the AR488 and can get the HP to respond to button press commands and rst, but i can't quite get an assembler to load. Honestly, I'm not even sure I'm sending it right. I've been trying to send the files via coolterm's send text/binary file function. The best I can get out of the 1630 is a CRC error. I have been able to successfully invoke the TC command but have not been able to reload the config that TC generates.
Thanks for any suggestions in advance
