I have a Mac IIsi and a sun 3/50 on my desk, connected through the
serial ports.  I can drive the serial port on the sun to 38400 baud, and
the Kermit I have on the mac (version 0.98(62) - 08/22/89) claims (in
the settings dialog box) to be able to go this fast (or even 57600 baud,
but I can't figure out how to get the sun to go that fast).  When using
kermit as a terminal emulator, I believe that I am getting 38400 baud,
but when I try to transfer files, I think I am only getting 9600 baud. 
There are two reasons why I think this -- 1) It takes a long time to
transfer large files, and 2) if I try to start kermit on the sun with -b
38400 it says invalid speed.  It says this for any speed greater than 9600.

So, does anyone have a sun3/unix version of kermit that will handle
higher speed data transfers?  Or a totally different file transfer
method that will allow higher speeds?  I am using MacLayers, which will
give 19200 baud, but I'd still like it to be faster.

Thanks, Trevor

P.S.  The reason I want this to be fast, is because I transfer
Postscript files to the sun for printing, and they often contain
graphics, and are in the .5 meg range.
