That's CP/M-80 2.2? You can find documentation for Kermit-80 on our
ftp site:

ftp://kermit.columbia.edu/kermit/a/

Some of the relevant files are:

cpkerm.txt User manual (plain text)
cpkerm.ps User manual (PostScript)
cpkerm.bwr A series of "beware" (hints and tips) files.
cpkerm.bw2 ...
cpkerm.bw3 ...
cpkerm.bw4 ...

It should. In Kermit 95, do this:

cd
set port com1 ; or whatever
set speed 9600 ; or whatever else the handheld uses
set flow none ; There's no flow control
set carrier-watch off ; You'll probably need this
cautious ; Use the most conservative file-transfer settings
server

Assuming you have your handheld connected to the PC with a null modem cable,
now you should be able to tell Kermit-80 to SEND any file. If it's a binary
file, first tell Kermit-80 to SET FILE-MODE BINARY. When you are finished,
give Kermit-80 a BYE command.
