Most likely your 2400-bps modem was slow enough to avoid data overruns in
VMS, but 19200 is fast enough to cause them (in the absence of adequate
flow control).
In any case, a lot has happened to C-Kermit since 5A(190) came out in 1994.
Pick up C-Kermit 7.0 from:
http://www.columbia.edu/kermit/ck70.html
Among other improvments, it knows how to set up a USR modem for dialing out
from VMS exactly as it needs to be (modem signals, flow control, etc).
