I'm seeing RS232.COM on SDX 4.49c fail to load in Altirra 3.10 with an 850 connected, but the RS232 handler will bootstrap everywhere else... Is there a setting I need to flip to get SDX to play nice?
SDX 4.49 perturbs the 850, you have to leave the device off during intitial sdx polling... then turn it on before use.. altira may need a power switch for the 850 as SDX 4.49 may be trying to access the 850's other modes by accident during it's polling process.
The behavior happens with 4.49d on real hardware as well. this is part of the reason why I posted to leave the 850 off until ready to load your driver and terminal program for folks new at this in the BBS thread.
Just like most of other things Atari... there is more to the 850 than meets the eye. I think Curt is a fan of the device as well. It is due for a complete probing and hacking, perhaps some tweaks to speed up a bit... believe it or not some of that's been done before- franken-roms- faster chips.
