I thought I would try the Dark Side, but I never liked CP/m. We have ways to get our Model Ts to talk to the computers we all have on our desks. Why torture them to do more? On Mon, 10/30/17, Philip Avery wrote: Subject: Re:

Hi Philip, Depending on the version of NADSBox firmware you have, you can already tell it to switch to 76,800 baud rate. This can be done either from a command line or via an extended TPDD protocol packet (version 1.16). From the command line, you would type one of the following: baud

Right, I need to go over to the dark side & use command line interface ;-)  I shall attempt that. What would be ultimately cool is use TBACK technology, ie a baud rate of 78,000 approx. As file sizes could be large (100KB or even full REX/Remem Ram of 2MB), this would be useful. How feasible

Yes, NADSBox supports it. It will auto-detect the 8.3 format for received packets and switch to that format. Or there is a persistent config option that can be set to enable it all the time (no auto-detect switching needed). Ken On 10/30/17 12:25 AM, John R. Hogerhuis wrote: Like I said

Thanks for doing that testing! Off the fop of my head I would say not. It has been a while since I looked at the code but if REX is automatically switching to a bad ROM image on power up..out of luck. Sounds like an emergency switch is needed. I personally don't like rom replacement. It is prone

Thanks John & Willard. My aim is for M100 CP/M to import/export using common TPDD emulators of today, namely NADSBox, Laddiecon, mComm. Perhaps if CP/M finds traction in the M100 community, Laddiecon & mComm could be changed to handle 8.3 format as well. Probably a bit late to change the
