TXFlow ON|OFF<br />
Default: OFF<br />
Mode: Packet<br />
Host: TF<br />
_________________________________ Parameters: _________________________________<br />
ON - Software flow control for the <strong>PK</strong>-<strong>232</strong> is activated in Transparent Mode.<br />
OFF - Software flow control for the <strong>PK</strong>-<strong>232</strong> is disabled in Transparent Mode.<br />
_______________________________________________________________________________<br />
When TXFLOW is ON, the setting of XFLOW determines the type of flow control used<br />
in Transparent Mode by the <strong>PK</strong>-<strong>232</strong> to control TRANSMITTED data.<br />
When TXFLOW is OFF, the <strong>PK</strong>-<strong>232</strong> uses only hardware flow control to control<br />
TRANSMITTED data; all data sent to the terminal remains fully transparent.<br />
When TXFLOW and XFLOW are ON, the <strong>PK</strong>-<strong>232</strong> uses the Start and Stop characters (set<br />
by XON and XOFF) to control the input from the computer.<br />

TXRev ON|OFF<br />
Default: OFF<br />
Mode: Baudot/ASCII/AMTOR<br />
Host: TX<br />
_________________________________ Parameters: _________________________________<br />
ON - Transmit data polarity is reversed (mark-space reversal).<br />
OFF - Transmit data polarity is normal.<br />
_______________________________________________________________________________<br />
Use the TXREV Command to reverse the mark and space in the transmitted AFSK and<br />
FSK signals.<br />
In some cases, the station you're working may be receiving inverted data<br />
although it is transmitting in correct polarity. Set TXREV ON to reverse the<br />
sense of your transmitted signals.<br />
TXREV only works on ABAUD and RBAUD at speeds up to 150 baud.<br />

UBit "n" ON/OFF Default: 0<br />
Mode: All<br />
Host: UB<br />
_________________________________ Parameters: _________________________________<br />
"n" - 0 to 255 specifying a User BIT that may be set ON or OFF.<br />
_______________________________________________________________________________<br />
The UBIT is an extension of the CUSTOM command which allows up to 255 ON/OFF<br />
functions to be added to the <strong>PK</strong>-<strong>232</strong> without burdening users with a large number<br />
of commands. The functions controlled by UBIT are not things that most users<br />
will ever have to change. Still they are important enough to some users or<br />
application programs that we have included them under the umbrella command UBIT.<br />
The following are examples of how to use the UBIT command:<br />
UBIT 5 Returns the present status of UBIT 5<br />
UBIT 1 ON Sets the function controlled by UBIT 1 to ON<br />
UBIT 10 T Toggles the state of the function controlled by UBIT 10<br />
UBIT<br />
Returns the state of the last UBIT value that was accessed<br />
