How can i use two serial ports?

I use that script: System/ports/serial:[com4] mx: open/binary/direct/no-wait serial://port1/38400/8/none/1 it works fine, but i need a second port on com3 to read data - how can i do this. close mx and set a new port does´t work many thanks

I would advise reading through the info on serial ports on http://www.codeconscious.com/rebol/rebol-net.html#SerialPorts see the following: 1) You must be running REBOL as ROOT (or somehow change the permissions on the serial ports beforehand) as this is a security feature of most multi-user systems. 2) Try setting system/ports/serial to the different naming conventions of your system. For example: system/ports/serial: [ttyC0 ttyC1] -or- system/ports/serial: [ttyS0 ttyS1] -or- system/ports/serial: [cua0 cua1] You can include as many serial ports as there are on your system in this block. 3) Open the serial port like this: serial-port: open serial://port1/9600/8/none/1 Use the word PORT1 above (don't replace with the serial port name) as it refers directly to a location in the system/ports/serial block. You can also use PORT2 or PORT3, etc. (if applicable to your system).

in other words, use PORT1 and PORT2 to refer to different ports from the system/ports/serial block and see if that works. I don't have all my serial devices out to play with to confirm.

Thank you for the fast reply !
