XMODEM is not exactly a robust protocol for financial transactions.
The bank should think again.

It's possible under C-Kermit too, at least in UNIX. For the past several
years, C-Kermit has had a "set protocol" command to let you set up external
protocols. This works in UNIX when the external protocol program uses
standard input and output.
This frequently requested feature has not been implemented in the VMS version
of C-Kermit yet. However, it's not too late to get it into C-Kermit 7.0.
Any VMS C programmers who would like to help and are comfortable with
sys$qio..(), subprocess manipulation, etc, please contact me.
Meanwhile, as noted in the current VMS C-Kermit documentation, there is a way
to accomplish the same thing "by hand". Quoting from CKVKER.BWR:
You can use the ZMODEM SZ and RZ commands as "external protocols" over a
connection you have established with C-Kermit, to a host or service that
does not support Kermit protocol. Start the file transfer on the remote
end, escape back to C-Kermit, give the SPAWN command, and then (for example):
$ define tt xxx:
$ rz
where xxx is the designation of the terminal device (TT or LTA) that you have
dialed out on. When the transfer is complete, LOGOUT from the SPAWN'd
subprocess and you'll be back at the C-Kermit prompt.
