- Fact of life: serial ports lose characters.
- A proper port will do so rarely, but your typical PC or workstation
- serial port loses a character occasionally. No problem for an online
- user session, pretty bad if you're transferring compressed data.

- I wouldn't worry about errors on the bus unless the system operated in
- an extreme environment. Depending on your degree of paranoia, parity or
- ECC-checked RAM might already look like a good idea.
-
- OTOH, limited character loss at a serial port is commonplace. And if you
- think PCs are bad in this respect, check out a Sun workstation.
