Non functional Applicard mode on firmware 145; also gets stuck in that mode

Setting the card to Applicard mode disables VGA. (By design.) But then the Applicard boot disk does not boot CPM, it just hangs at a black screen when looking at Composite video. (CPM disk works on a real Applicard on the same machine.)
Trying to change back to VGA mode fails because the config utility reports time-out.
I had to use the ML monitor to manually switch back to VGA mode by writting:
C=VGA and then DC at C4F0h. (My card is in slot 4.) Card comes back to life and work again.
Config utility can communicate with the card again.
Build 0159 has working PCPI mode, but escaping back is still finicky.
The FORMAT command is more appropriate, as sending the DC command with all zeros will upload $0000-$03FF as the config file of the card and could cause further problems.
Replace n with the slot number the card is installed in:
]CALL -151
*CnF0:46 4F 52 4D 41 54 00 00
This is working great now. I had to format the card to get out of PCPI mode, but I was able to boot into CPM without issue. Excellent!
