LocalTalk => dropped chars. in ProTERM?

[tschmidt@magnus.acs.ohio-state.edu (Tim Schmidt)]

I've got my IIGS set up using a Mac IIsi as a file server over LocalTalk.
I have a 9600 baud modem that I switch between the two computers.  When
using it on the IIGS with ProTERM 3.1, it tends to drop sets of two
characters with annoying frequency.  On the Mac, the modem loses no
characters.  Is this a known result of the LocalTalk interrupts?  If I
turn off LocalTalk, will the problem go away?  Is there any *other*
solution?  (I love having all my files on the Mac's drive, but still
accessable in ProTERM via the mini network.)

Thanks,
  Tim
