wide mode detection for model I on TRS32

Hello everyone,

I'm investigating a problem with my trs-80 game using trs32 under windows for the model I.

My code tries to find whether the model I is in wide character mode. I thought this could be achieved by examining bit 6 (ie mask 0x40) reading port 0xff. This is indeed the case under SDLTRS. 1=>wide, 0=>normal.

However, recent versions (eg 1.28) of TRS32 do not report this (worked for old versions). It appears trs32 reports the inverted bit, ie 1=>normal, 0=> wide.

For example, in trs32 in BASIC

PRINT INP(255) gives 127

then

PRINT CHR$(23)
PRINT INP(255) gives 63

trying the same commands in SDLTRS gives the opposite values.

Which is correct? If you have a real model I handy, I'd be very interested to know what the above basic commands give on the real machine.

thanks for any help,
