This was to alleviate bugs in SENDING TO the sun. Never had problems receiving.

That's Ymodem block 138, $8A. That means it had troubles on the next
block - $8B. See more below.

That's odd. I always type 'sb <file>' to send to Z-Link. Typing 'sz'
just momentarily confuses things as the unix side tries to send with
Zmodem. When Z-Link NAKs it to death, sz steps down to ymodem.

On the other hand, I've never had problems. It's the only way I ever
send anything back and forth. Are YOU being routed through a terminal
concentrator or just trying to send through a TELNET session? Every
layer of software you go through adds to the various troubles you can
have. Z-Link will eventually do kermit, but don't hold your breath - I
have to graduate this term (somebody hire me!).

When you try sending with Xmodem ('sx file'), where does it die?
Betcha at byte 17664. That's also block $8A (last good one to come
over). If so, then I'd bet that some piece of software is munching
$8B's.

My employer pays me well. This, however, does not mean he agrees with me.
I wrote Z-Link & BinSCII. Send me bug reports. I use a //GS. Send me Tech Info.
