Brad,
This may help. I have a LB12, LB15(osp5000L), and 2 cadets( 1 w/5020 and the other w/700 control). My LB15 is the one I currently have some problems with.
I'm using ProComm software. On the LB15, we get most of the program but are still losing some characters.
I'm still working on a resolution, getting close. It's either a "bit" or the "baud rate".
Try this and see how it goes
bit 1 to 00001011
bit 12 to 00000000
optional parameter word:
#1 to 1
#2 to 30
#10 to 8(I've been moving this "baud" number around to see what happens)
For "loading" program into machine tool try PIP/READ then TT

hit write key)
For "punching" program out of machine try PIP/PUNCH <file name>,TT

hit write key)
Let me know if this helps. I'm having trouble w/our local Okuma dist. trying to solve.
I'm curious if Gosiger as able to resolve your problem.
Please let me know either way.
Good Luck,
Duke
