(Bugs?)

Has anyone in netland had any problems with the IBM Professional Graphics 
interfering with serial communications?  I have been using my PC/AT for
months and often as a terminal to various mainframes.  I have used both
the IBM 3101 terminal emulation package (works poorly on the AT), and
KERMIT 2.27's H19 terminal emulator.  I used to use the serial port
connected to the Sytek LocalNet at speeds from 1200 to 9600 baud, but
since the addition of the Professional Graphics I cannot handle speeds
greater than 1200.  I can't think of what is causing the problem?  Are
the graphics boards driven at such a higher interupt priority that the
serial port looses out?  Occasionally I have trouble even at 1200 baud.
The only other change to the system is the inclusion of the Graphic
Designer Toolkit device drivers in the CONFIG.SYS file.  Thanks for you
