I 've had my Paragon talking to Logger 32 via the 25 pin serial port for 
some time, but tried today to use it on CW in this configuration.  This 
Paragon has the Ghiel chip.  The rig is being keyed by a stand  alone 
keyer, NOT via the computer

I immediately noticed that when a string of dits were sent at about 25 WPM, 
the rig missed sending some from time to time. Some investigation showed it 
was much the same time needed to digest the frequency knob being turned 
rapidly, before the computer caught up with the new CW setting.  It's like 
it can send 20 or so dits, then the rig comes out of transmit for 3 or 4 
dits while the serial port buffer gets emptied, then another stream of dits 
is ok,  etc etc.... I can hold the keyer paddle down with a steady stream 
of dits, but the rig periodically drops in and out of transmit.

Unplug the serial connector, all is fine.   The computer is certainly fast 
enough, but am I correct in thinking that the 1200 baud capability of the 
Paragon computer interface can't keep up with such things?
