abusing kermit for Xmodem uploads

Hi,

I'm trying to do Xmodem uploads from a NetBSD 2.0 system to a
Soekris net4501 using kermit and lrzsz. I know how to do this
using tip(1)/cu(1) and lrzsz, but I'd like to achieve the same
using kermit. However, I've never used kermit before...

When using tip, I connect to the corresponding serial port, use
the "download" to put the net4501 in "receive mode", use tip's ~C
escape to fork a child process, and start uploading the file
with "lsz -X file".

How can I do this with kermit? So far I tried the following kermit
commands:

set protocol xmodem-crc download {} {lsx %s} {} {lrx %s} {}
set line /dev/tty00
set speed 9600
set carrier-watch off
set flow-control xon/xoff
send /binary file

but this fails:

Sending file, 608 blocks: Give your local XMODEM receive command now.
Xmodem sectors/kbytes sent: 0/ 0kRetry 0: Got 52 for sector ACK
Retry 0: NAK on sector
Retry 0: Got 20 for sector ACK
Retry 0: Cancelled

Transfer incomplete

*************************
SEND-class command failed.
Packets sent: 0
Retransmissions: 0
Timeouts: 0
Damaged packets: 0

HINTS... If the preceding error message does not explain the failure:
. Did you start a Kermit receiver on the far end?
. Try it again with SET STREAMING OFF.
. Try it again with SET PARITY SPACE.
. As a last resort, give a ROBUST command and try again.
Also:
. Be sure the source file has read permission.
. Be sure the target directory has write permission.
(Use SET HINTS OFF to suppress hints.)
*************************

A diff between stty outputs when using tip and when using kermit
gives:

$ diff tty00.kermit tty00.tip
5,6c5,6
< iflags: -istrip -icrnl -inlcr -igncr ixon ixoff -ixany imaxbel ignbrk
< brkint -inpck ignpar -parmrk
---[color=blue]
> iflags: -istrip -icrnl -inlcr -igncr ixon ixoff ixany imaxbel -ignbrk
> brkint -inpck -ignpar -parmrk[/color]

Help is appreciated!
