check out /proc/tty/driver/serial

serinfo:1.0 driver:4.27
0: uart:16550A port:3F8 irq:4 baud:1200 tx:8 rx:6249 brk:1 RTS|DTR
1: uart:16550A port:2F8 irq:3 baud:115200 tx:5032122 rx:65579052 brk:4 RTS|CTS|DTR|DSR|CD

my ttyS0 is mouse and ttyS1 is modem which is currently connected, i don't

the tx/rx stats appear to be cumulative, they don't reset when the modem goes
