NAME

hty_tally − display MVME338 channel information

SYNOPSIS

hty_tally [-c ] [ -d device ] chan_num

DESCRIPTION

Hty_tally uses the MVME338 raw driver to retrieve channel statistics for an open channel (specified as a decimal value in chan_num ) from an MVME338 board.  Hty_tally retrieves this information by issuing a number of internal commands to the Terminal Control Software and interpreting the resulting data.  The parameters are written to standard output. 
 
Note that the channel number is relative to the board.  Each board’s channel numbers start at 0.  This does not necessarily correspond to UNIX minor device numbers.
 
The information displayed shows counts for the characters read and written, and various modem signal events, such as framing errors, parity errors, BREAKs recieved, overrun errors, and signal transitions since the last time the mvme338 was downloaded, or the tally counts for this channel were cleared.

OPTIONS

One or more of the following options may be selected:

−cClear the tally counts for this channel after displaying them. 

−dSet device file name.  This option overrides the default device name. 

EXAMPLES

To write a formatted display of the tally counts for channel 0 of the first MVME338 to standard output:

 hty_tally 0
 TCS tally info for 0:
Characters read              0   Characters written           0
Framing errors               0   Parity errors                0
Overrun errors               0   Breaks received              0
DTR transitions              0   RTS transitions              0
CD transitions               1   Failed ports                 0
Online transitions           1
 

To write a formatted display of the tally counts for channel 56 of the second controller to standard output:

 hty_tally -d /dev/xedt/mvme338_c1 56
