Ports

8.9.4 Padding Return Characters

By default, the SCS will pad Carriage Returns entered in Telnet sessions with null characters. To disable
this characteristic, use the Set/Define Ports Telnet Pad command.
Local>> DEFINE PORT 3 TELNET PAD DISABLED

8.9.5 Setting the Device Type

The Type characteristic is used to specify the device types compatible with the port. Type must be one of
the following device types: ANSI, Hardcopy, or Softcopy. To set a Type, use the following command:
Local>> DEFINE PORT 3 TYPE ANSI
For more information about Type options, refer to Set/Define Ports Type on page
Note:
12-90

8.9.6 Specifying a Terminal Type

A terminal type, to be sent to the remote host for Telnet and Rlogin sessions, can be specified for a port using
the Set/Define Ports Termtype command. The terminal type should be entered as a string, for example,
VT100.
Local>> DEFINE PORT ALL TERMTYPE IBM1000
By default, no specific terminal type is specified.
Note:
Termtype information is used for outbound sessions; the SCS doesn't use this information. For example, a
remote host might use the terminal type to configure your terminal to run a particular application.

8.9.7 Transmitting Serial Data

Serial data can be handled a couple of different ways. The default settings will discard all data. Other options
include setting various triggers to transmit the accumulated data to a host.
Once a connection has been started, several different triggers can be used to transmit all accumulated serial
data to the host. These options are controlled with the Set/Define Ports Datasend command. The datasend
process used by the SCS balances network traffic with latency concerns.
One kind of trigger can be set by specifying a "timeout" condition of either the time since the last character
was received or the time since the current character burst was started. For example, to trigger data
transmission 150 milliseconds after the current character burst began, enter the following command:
Local>> DEFINE PORT 2 DATASEND TIMEOUT FRAME 150
