How to multiply/mix USB and RX/TX pins on uno without SoftwareSerial because i use Bitlash for BASICs Base, and use PRINT() for custom functions (other uno will give it back and 1st arduino get again. but theres a problem, Bitlash only supports hardware serial and commands coming from USB but Expansion/2st arduino also communicate. theres 1 hardware serial i dont know how to mix HardWare Serials (9600 baud) also site VERY glitchy everywhere is like tiles replaced on NES

you can't. Uno has one RX/TX hardware pair, and it is used for USB. So you're foxed.
A Mega has 4 serial sets, other Arduino creations have more than one. That's where you'll have to go.
C

Use a different Arduino.

nano?,pro mini? well i dont have any megas

Then get one.

also is it possible to make half hardware half software serials?

Frankly, the Arduino.cc site should have a table comparing features of the various boards. A brief search didn't turn one up, which doesn't surprise me, but you should be able to locate one on the web.
try this?
C

You would need to explain exactly what you mean by that.

they has the same chip as Uno so the problems will be same
