Data loss should not happen with flow control on. Please contact
myself directly, or our support (support@con...) desk to open a call.
Otherwise I'll have to look at it in my CFT.

Things I'll need to know:
- kernel version :: 2.4.18-10
- distribution version :: RedHat ??
- serial driver version :: ??
  (this is reported at boot, cat /var/log/messages or dmesg)
- are you using our official driver + patch set?

We're using Exars as well, although perhaps not the rev D.
