We have many older Hurco machines both Max 2 and Max 3 era. We have lost the disk drives on a couple of the older Max 2's and are finding it harder and harder to find replacements. I am wanting to use the RS232 communications to try back up the programs and was trying to use Procomm the same as I do on an older Nagitta mill. I was hoping someone could help and let me know if this could be done. I know you can use the Conversational up/down program from Hurco but I was hoping to be able to keep using the program we are currently using (Procomm) to do the same. Thanks
