Yep.  That is all very well for my 32 bit app, but the 16 bit - works
OK, unless you try a comm trace, then it crashes, with this little
beauty:

trace:comm:WriteComm16 cid 3, ptr 0x40f7d21e, length 1487
wine_dbg_vprintf: debugstr buffer overflow (contents: 'trace:comm:WriteComm16 1A2845F7:       4:PUTDATA 541 AD_STATS 0.AS

I guess 1407 bytes plus the trace message is more than we need.

Also, the app shuts off CRTSCTS.  I think there is still something wrong
in [GS]etCommState16 and/or DCBtoDCB16.
