I am trying to attach a Printronix P-300 line printer to a Sun 3/260
running SunOS 3.5. A breakout box confirms that the printer is operating
correctly and the cable is correct. The problem is that the Printronix
does not support XON/XOFF and the Sun is not paying attention to the
hardware handshaking. I made a new kernel with carrier detect enabled, but
all that gets me is lpd continually restarting the print job. The Sun does
not seem to be interpreting the local mode bits (xs capability) the way
tty(4) implies. Any suggestions would be appreciated. The printcap entry I
am using is:

eb244_lp|Case Printronix P-300 line printer (DEFAULT):\
	:lp=/dev/ttyb:\
	:sd=/usr/spool/lp_sd12:\
	:lf=/dev/null:\
	:br#9600:fc#0171777:fs#0006000:xc#0177317:xs#0000460:mx#50:sc:

Please email to me and I will summarize.
