I have no problem sending or receiving programs to my mills but I can not get the settings on the lathes to work.

the lathes are old as dirt Miyano 7BC (before crist) and I have no book to tell me the pramiter settings are.

I know that the baud rate is 2400 and I have tried almost every combonation of settings in Cimco and all I get is errors.

can anyone help ???????????
