Nice scramble.  <g>  Your posting was at least unclear, since you did *not*
"connect" at 38400, and since a serial port speed of 38400 can be used for
*any* connect speed (even 2400 bps).

That wouldn't seem terribly important for a support BBS where bulk
compressible text transfers are relatively rare.  Or am I missing
something?  ;-)

Then there is something wrong with your system -- I use 57600 (or higher)
for *all* connections without any problems.
