This is a somewhat older version of Kermit-11 - it may be the newer one
(T3.60) will do better here. This is available by anonymous ftp from
kermit.columbia.edu in the kermit/b directory. If getting it on to the
PDP-11 is a problem you may need to transfer and then decode a hex
encoded version of the K11 image. Instructions for doing this are in
a file in the same directory named krthex.mac - this concerns RT-11 so
you'll need to determine how to get PIP (a utility program) to accept
input from the terminal (a rather minor detail). The hex encoded images
have the file extension .hex - also k11pos is I believe for the Pro-300
series of PC-type systems DEC built in the mid-1980s so it may be some
other assembly of Kermit-11 would do better on a real PDP-11.
I've been maintaining and updating the RT-11 version of this for some
years now and recall various comments in the code regarding problems
with things in RSX changing as new versions of that were released.
You'll likely be able to find some people familiar with RSX in the
alt.sys.pdp11 and vmsnet.pdp-11 newsgroups. In particular Johnny
Billquist at Upsala University in Sweeden may be familiar with what
will run properly in this case, or know what is necessary to fix it.
Long packet support means this Kermit is capable of using packets
greater than 94 bytes long. I beleive the upper limit in the version
you have is 600 bytes. This isn't much by today's standards but every
little bit helps. To enable use of long packets on Kermit-11 you'll
need to SET RECEIVE PACKET-LENGTH 600.
