I just came across something very perplexing, and I was hoping someone out in 
net.land might have an idea.  I have been writing a game to be played across
the modem between two computers.  It works pretty well, except occasionally it
will get "confused".  I tracked it down and it appears that 0x11 is not being
transmitted.  I dumped the characters just before I wrote them to the serial
device, and had the receiving computer dump everything it received.  All the
characters were transmitted except for 0x11.  I reproduced it several times
each time when a 0x11 should have been sent it "disappeared".  

I am using a Supra 2400 modem.  The program is written in C and just uses pretty 
typical IO, (i.e. Opens the serial.device and issues a write command specifying 
the string and its length) and of course it works for everything but the 
character with a value of 0x11.
