My Epson PostScript printer is connected with a full null-modem cable to a serial port using a 16550 UART. All works fine, except when I´m printing more than 2 (approx.) pages the printer gives an ioerror. OS is FreeBSD-2.2.2RELEASE, the printer is set to 38400,8,n,1 Xon/Xoff printcap entry: laser|Epson EPL-7500:\ :sh:sd=/var/spool/lpd/laser:sc:mx#0:\ :lf=/var/log/lpd-errs:\ :lp=/dev/ttyd1:br#38400:fs#0x082000c1:rw:\ :if=/usr/local/libexec/psif:\ :if=/usr/local/libexec/psdf: It seems that somehow the Xoff is lost somewhere. I don´t know if I´ve set the flags wrong, or if the 16550 is the problem (printer has no RTS/CTS flow controll). Thanks, Roland
