Send command to device attached to COM1
/
cgi-bin/senddata.cgi?com=1&data=123456,ABCDEF&flush=yes&wait=1000&read=6
This hyperlink will inform the VPort 2141 to send out binary format commands to COM1 with
“0x12, 0x34, 0x56” followed by “0xAB, 0xCD, 0xEF”. Each comma separates the commands by
200 milliseconds. “flush=yes” means the receive data buffer of the COM port must be cleared
before it is read. Then read 6 bytes after waiting for 1000 milliseconds. The read data can be up to
128 bytes and will return as ASCII coded hexadecimal value, e.g., 0x41, 0x42, 0x43 read from
COM port will show in the returned homepage as 414243 instead of ABC.

/cgi-bin/senddata.cgi?com=2&data=123456,,,ABCDEF
