I have been using DOSemu in conjunction with Debian versions 5, 6 and 7, together with a number of different physical computers, and have found it very useful indeed. It provides me with the ability to back up a hand-held device via a serial cable and proprietary program written for MS-DOS. With all of these setups I have installed the version of DOSemu from the Debian repository. In all cases I have found it sufficient to insert one of the following lines in /etc/dosemu/dosemu.conf in order to identify the serial port. $_com1 = "/dev/ttyS0" $_com1 = "/dev/ttyUSB0" >From this you can see that I have used both inbuilt serial ports (ie on the motherboard) as well as USB serial port adapters. The only other modification necessary has been to use one of the following commands in order to gain access to the serial port. chmod 666 /dev/ttyS0 chmod 666 /dev/ttyUSB0 Recently I bought a new computer and installed Debian version 8, together with DOSemu 1.4.0.7 from the standard repository. I made the usual adjustments as above. The emulation started and ran normally but serial communication failed. I tried the USB adapter in place of the motherboad COM port, but to no avail. I tested the connecting hardware using a different computer running Debian 7 and all was in working order. I solved the problem by using an older repository and forcing the installation of DOSemu version 1.4.0.1, after which everthing worked normally. I thought it might be helpful to let you know. -- To unsubscribe from this list: send the line "unsubscribe linux-msdos" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
