You can play with 2 xmodem tuning parameters.
Parameters are changed like so:
boot> set
The changes are not permanent unless you do a
boot> params save
The 2 xmodem parameters are:
xmodem_initial_timeout
xmodem_timeout
xmodem_initial_timeout is the timeout used for the first byte of
the xfer. Once a timeout is gotten on a char, xmodem switches to the
xmodem_timeout value. This allows our xmodem to be fitted to various
xmodem senders. In particular, minicom and hyperterm have different
requirements. minicom would be happy w/fairly quick initial and long
secondary, hypnoterm would like short/short.
Minicom: once the send menu is entered, minicom/xmodem begins queuing
characters. Xmodem on the rx (bootldr) side sends a NAK to start the
xfer and then sends NAKs whenever it times out on receiving a block.
If the sender takes too long to begin a send, then xmodem can end up
with >1 NAKs queued. This then confuses xmodem and we get the
mega-errors problem.
xmodem_initial_timeout should be long enough to get into the
xmodem menu so that xmodem will rx and queue the NAK sent by the
bootldr.
xmodem_timeout should be very long to make sure that more than one NAK
is not queued by minicom while the user is navigating the file system
in order to select the file to download. I use 0xffff for initial and
leave the other param alone.
Hippoterm: Does not queue naks, so short/short is best,
e.g. 0xffff/0xffff, since hyperterm will start sending on the
next NAK after the file name is selected. I don't use hypertomb, so I
don't know how well these numbers actually work.
