Starting the TN3270e Server
This space must be available on the swap volume. You can change the
amount of swap space allocated for the buffer segment with the -m command
line option described later.
The TN3270e server ignores any IN or OUT file specification. However, if an IN or OUT
file is specified, it must be one of the following file types:

Odd-unstructured (code 180)

EDIT (code 101)

Process

Terminal
The following command line arguments are used by the TN3270e server:
port
is a decimal number that specifies the TCP/IP port number over which connections
will be accepted. If the port number is 1023 or less, a super group user (255,nn)
must start the TN3270e server. The port number must be unique among all TCP/IP
services accessing a single TCP/IP process. port number is required; there is no
default value.
etn32-options
specifies one or more command line options, which you enter separated by spaces
(spaces are not permitted within an option). For example, when using the -mpages
option, enter it as -m1020 for 1020 pages, with no spaces between the -m and the
1020.
-bsize
specifies the size of each socket read request in bytes. This parameter
overrides the default socket read size of 2048 bytes. Since the total PFS buffer
size is 1 megabyte, and the TN3270e server posts a read for each TCP/IP
session, the total PFS buffer space is exhausted with 512 sessions active.
Reducing the read size potentially results in more I/O overhead but allows
more than 512 reads to be simultaneously active.
-cnumber
specifies NonStop mode operation. number is the CPU number (0 through 15)
on which to run the backup process. If this option is omitted, ETN32SRV
operates as a single process.
-f
forces a Saveabend file to be produced automatically in most circumstances
when the TN3270e server abends. For common startup errors, the Saveabend
file is suppressed.
