5-10 Syntax and Parameters
MX2 Reference Guide Revision A MX2A137REFGD
The C option can be used in conjunction with the O option. If you
specify C2 (follow sender) on the command line, the receiver will use
the sender’s crash and overwrite options. Any overwrite options local to
the receiver will be ignored. This is useful if a default crash-recovery
command is specified in the XFER_ARGS environment variable and
you wish to temporarily disable crash recovery for the current transfer.
D#
Delay Before Terminating Transmission
This option allows you to specify a timeout. If the specified number of
seconds elapse with no characters received by either the sender or the
receiver, the program aborts the transfer session.
For multiple file transfers in Zmodem, the entire session is aborted, not
just the transfer of the current file.
To use the D option, replace the # symbol with the desired number of
seconds for the timeout delay.
Acceptable values are 0 (no timeout) through 65,535; the default is 60.
A value of 0 disables the timeout feature, meaning that the transfer
session will never be aborted because of inactivity. If you use the D
option without specifying a number, an error will occur.
E#
Maximum Number of Errors Before Aborting Transfer
The E option allows you to specify the maximum number of times the
receiver will request a retransmission of a packet before aborting the
transfer session.
Note: For multiple file transfers in Zmodem, the entire session is
aborted, not just the transfer of the current file.
For Xmodem, the default is 0, meaning that Xmodem will never be
aborted because of errors. For Zmodem, the default is 30. A setting of 0
disables the error-count tracking. If you use the E option without
specifying a number, an error will occur.
