While this combination works fine in connection with a PC-compatible computer, I have problems in connecting the printer to my Macintosh II cx. The setup I am using is as follows: - Apple's Asynchronous LaserWriter Driver 4.0 - System 6.0.4 - Cable with TxD, RxD and HskO (to printer DSR/CTS) connected, attached to the Mac's modem port - Printer set to 9600 Baud, 8 databits, no parity, 1 stop bit This configuration was successfully tested with a LaserWriter II NTX (with two stop bits, of course), configured with its 25-pin connector as input. However, it does not run with the HP LaserJet II. I _am_ able to talk to the LaserJet II printer through a terminal emulation program; e.g., PostScript's executive mode works flawlessly. The problem seems to be the LaserWriter Driver; the Driver is obviously able to establish an initial connection to the printer (commands in the file "Direct.ACL"). After processing the ACL commands (Exit 0), the driver sends the sequence with a very short pause between the two characters. Since the LaserJet isn't very fast, it possibly doesn't recognize the status request and never sends an answer. As a result I get the following message on the screen: "status: connection unsuccessful - LaserWriter not responding". Observation: After a is sent, it can take up to 6 seconds until the printer returns to the idle state. The specific questions I have (other than: "how can I make it work ?") are: a) how can the Asynchronous LaserWriter Driver be changed to either make a longer pause between and or not send the at all (this is already done in the ACL file, and therefore not necessary) ? b) am I using the latest version of the Asynchronous LW driver; is there a newer version that contains a fix for this problem ? Thanks for any help ! - Mathias Myka Memmingen, Federal Republic of Germany E-Mail: ...!unido!cosmo!mathmyka (mathmyka@cosmo.UUCP) ommand must be the first word on a line. More than one command can
