I'm not sure about Linux but you MUST use some sort of flow control even
when the line speed (DCE rate) approximates the computer <-> modem rate
(DTE). Errors just become more obvious where there is a greater disparity
between the two. 

For an '8-bit transparent' transport as compressed UUCP news bundles
require, your only real choice is to use RTS/CTS handshaking. Set S58=2 and
leave S68=255 as you have it .. then explore how to get Linux to work with
it.

: When I want a PEP connection, I have to run minicom and manually set
: ATS50=255 and S51=5.  I'd like to be able to leave the modem locked at
: 19200, regardless of the actual connection speed.

S51=5 will achieve that by itself, even with a 2400 baud caller. It's the
missing RTS/CTS flow control that's causing the problem,
