Linux Virtual COM user manual
Using TTYredirector
All settings for new device(s) are default values.
If a device exists, there is no error.
No other options can be used with this command.
NOTE: The Linux kernel limits the number of Unix98 pty devices to a maximum of 2048, and most Linux distributions are
configured for 256 by default. Since pty devices are used for various purposes, the number available to be used by
TTYredirector will be lower, depending on what other software is running at the time.
trconfig -deltty dev
Deletes the TTYredirector TTY device(s).
If a device does not exist, there is no error.
No other options can be used with this command.
trconfig -ttylist dev
trconfig -l dev
Forces the set of TTYredirector TTY devices to be exactly dev, adding them as necessary.
Existing TTY devices not in dev are deleted.
No other options can be used with this command.
B. Location of the networked device
trconfig -tty dev -server IP-addr -port TCP-port
trconfig -y dev -s IP-addr -p TCP-port
IP-addr — A numeric IP address xxx.xxx.xxx.xxx or a hostname of the device server
TCP-port — The TCP port number at which the device server accepts connections for the specific device
C. Protocol supported by the device server
trconfig -tty dev -protocol tcp|telnet|telnetcr
trconfig -y dev -o tcp|telnet|telnetcr
tcp — Raw TCP connections only (default value)
telnet — Telnet protocol, with or without RFC 2217 extensions
telnetcr — Telnet protocol with CR padding
D. Automatically log into device server
trconfig -tty dev -auth username|none
trconfig -y dev -a username|none
username — At the beginning of a connection, attempt to detect and respond to a login prompt from the server asking
for a user name.
none — Do not detect any server login prompt. (default)
trconfig -tty dev -username name -password pwd
trconfig -y dev -u name -w pwd
username — Use this name to respond to a username prompt.
