Zmodem trouble

[Hong Zhang]

I had trouble uploading files to a remote Sun Sparc 1+ through zmodem.  It
always got stuck after transfering about 16K bytes.  After displaying a
message "got ZRPOS",  it would try "Error Recovery" on the same byte
forever.  If I interrupted the receiving, I would never get back to the
shell.  The only way out was to disconnect the phone and to make another
long-distance call.

I have tried several versions of zmodem on both sun and pc sides.  They
all gave identical results.

Your comments are greatly appreciated.
