PromLink under dosemu

PromLink under dosemu

[Lars Bjørndal]

Hi!

I try to get access to a dos program called Promlink, which I can use
to communicate with a device that burns EPROMs over the serial
interface. It works under real dos, but not under dosemu (1.3.0.1).
I've set $com1 = "/dev/ttyS1" in /etc/dosemu/dosemu.conf. Have also
tried to init the serial port before starting dosemu with stty. No
luck. Any tips?

Normally COM1 is /dev/ttyS0 in Linux. So you have to set

$_com1 = "/dev/ttyS0"

In 1.3.0.1 you have to set $_ttylocks because dosemu wants to write a lock 
file for the serial port. This lock file should go to /var/run. But as normal 
user you don't have the right to write in /var/run. So tell dosemu to write 
the lock file for example to 

$_ttylocks = "/home/user/.dosemu"

or somewhere else.

If it doesn't run look at /home/user/.dosemu/boot.log for information why you 
can't reach the serial port.

Not the latest version.

"No luck" is not a bug-report.

Yes, but I want to use com2, so com2 = "/dev/ttyS1" should be right. Or?

Yes, but I run dosemu as root.

It looks fine: register /dev/ttyS1 serial

And I may copy a file to a printer, which I sometimes connect to com2.

It should work, what COM port are you connecting the device to?  ttyS1 is 
COM2, which will mean that your physical COM2 port is being referenced by 
COM1 when in dosemu.

I installed the current CVS version of Dosemu, and no, all works fine!

Thanks!
