The symptoms you describe are typical of having XON/XOFF flow control
utilized by some external device.  The sector number for you are losing it
on is...XOFF!!!    Nec 2431 modems do automatic XON/XOF, and so do some
LANS and datakit.   One way around it is to use KERMIT instead of xmodem.

Other alternatives include checking the modem options on both ends, and
any data switch (LAN or Datakit) you happen to go through.  If it's a 
Unix system, try dialing in on the port used for UUCP.  UUCP can't handle
flow control either.
