4-6-2 CR command
abbrev. CR default: ON parameter: ON/OFF
example: CR ON
This command determines if the [CR] code is added (or not) at the end of the I-frame
transmission. [CR] is added if ON is chosen. [CR] won’t be added if OFF is chosen. Normally, the
SENDPAC command does not include [CR] when it makes an I frame, as it is already “$0D”=[CR].
In this case, when this parameter is ON, [CR] is added after the I frame. As a result, [CR] code
will be left.
4-6-3
PACLEN command
Abbrev. P default: 128 parameter: 0-255
Example: P 78
When the number of input characters (bites to be exact) reach this parameter, the data will be
considered as a packet (I frame) and sent.
4-6-4
PACTIME command
Abbrev. PACT default: AFTER 10 parameter: EVERY/AFTER 0-250
Example: PACT A 10
This command was originally for the transparent mode, which is not supported by this unit.
When the CPACTIME command, which will be explained later is set ON, this command becomes
effective in the converse mode.
The prefix EVERY (abbrev.E) is selected, the input characters will be considered as an I frame at
every interval identified in the parameter setting. The parameter is set in units of 100ms. Nothing
will be sent if nothing is input during the identified interval.
If the prefix AFTER (abbrev. A) is selected, the packet(I frame) is sent after the time set when the
time identified by the number has elapsed.
4-6-5
CPACTIME command
Abbrev. CP default: OFF parameter: ON/OFF
Example: CP OFF
This is to determine if the PACTIME command becomes effective (or not) while in the converse
mode. The PACTIME command becomes effective when ON is selected. The PACTIME command
is not automatically effective on the EJ-41U.
4-6-6
MAXFRAME command
Abbrev. : MAX default: 4 parameter: 1-7
Example: MAX 7
This command sets a limit on the number of packets that have not been acknowledged by the
receiving station. Since the size of the EJ-41U’s transmission buffer is limited, the number of
outstanding frames and the size of those frames must be considered. The maximum size and the
