Hi all,
I have a serial device connected to COM1 on a Windows 2000 machine,
and I'd like to be able to access the device remotely - e.g. via SSH.
I have set up Cygwin's sshd, so I can log into the windows machine via
SSH. Ideally I'd like to compile ckermit under cygwin, but I'd be
willing to pay for Kermit 95 if it could do what I want. I'm having
two problems with Kermit 95:
1. The trial version won't run remotely, because it tries to pop up a
GUI window to remind me about the trial. I assume this will go away
once I register, but can someone confirm that? i.e. Running k95.exe
doesn't open a GUI window once it's registered?
2. In order to run in a cygwin window or over an SSH connection, I
have to run k95.exe -# 96 to tell kermit to use stdin/stdout instead
of the Windows console. This partially works, but stdin seems to be
line-buffered, so that the serial device doesn't see my input until I
press return. Is there some way around this? ckermit does exactly
what i want: it doesn't do any terminal emulation or buffering but
gives me a direct connection to the COM-port's I/O, so the local
terminal can do its thing. Too bad ckermit won't run on Windows.
Another possibility I looked into was to use an iksd server instead of
sshd, but iksd disables the "set port" command I need to use to
connect to the serial port. Perhaps I could use the old "host mode"
instead, and modify it so that it allows the serial connection?
In case it's not clear, here's a diagram of what I want to do:
