Sounds like your line isn't 8bit clean.  I don't know enough about 
pppd to tell you how to fix it, but I think it's something like 
``asyncmap 000a0000'' in your options file.  You may also want to 
try removing the ``crtscts'' or ensuring that your modem's got an 
AT&F1 (I think that's the USR string) to configure hardware flow 
control.

In ppp(8) you can just ``set accmap 000a0000'' and maybe ``set 
crtscts off''.
