Mauro, PCMCIA serial port cards are available (just search the net for them). Here is one such card that has two serial ports: (URL) those cards aren't too cheap but old 14.4/28.8kbps PCMCIA modems are, perhaps making your own will suffice: (URL) (...) (23 years ago, 3-Jul-02, to lugnet.robotics)

The USB tower gets its power from the USB port. It has no battery, AND it stay "alive" all the time (unlike the old serial tower that timed out to save battery life). The only problems I've read about in the sdk package about using the USB tower on (...) (23 years ago, 3-Jul-02, to lugnet.robotics)

Unfortunatelly I can't buy that at Brazil. I want to buy a RIS 2.0 when possible but if I buy it here it would cost over US$300! I prefer to buy the whole set than individual pieces. It is more cost effective. Meanwhile I'm using my desktop (...) (23 years ago, 3-Jul-02, to lugnet.robotics)

Here it is... : wait 15 0 timer_SET BEGIN 0 timer_GET 0= UNTIL ; I go with 0,15 seconds to be on the safe side; 0,10 seconds is too border line. So now, the first example becomes: : TEST 100 0 DO I CR . wait 7 1 0 MOTOR_SET LOOP 7 4 0 MOTOR_SET ; (...) (23 years ago, 3-Jul-02, to lugnet.robotics.rcx.pbforth)

Thanks a lot Ralph, And I'm sure you're right. I tried this: 10000 VALUE CTR : test 100 0 DO I CR . CTR 0 DO LOOP LOOP ; For CTR > 11000, the numbers are displayed one at a time. Below 11000, they're displayed in batch. So, it probably means that (...) (23 years ago, 3-Jul-02, to lugnet.robotics.rcx.pbforth)

I just bought the usb IR tower from Lego Dacta www.pldstore.com and the RIS 2.0 upgrade kit from Lego S@H. cost me about $40 US, but that USB/Serial adapter was twice that when I went looking (...)
